Abstract

Background

Screw retained implant prostheses seem to be an efficient restorative method to prevent peri-implantitis caused by cement excess around the abutment. The drawback of the screw-retained prostheses is the difficulty to realize an efficient access-hole filling functionally and aesthetically. Up to now, few in vitro and in vivo studies were reported in the literature. The aim of this study was to evaluate clinical performances of two direct filling materials through a period of 12 months.

Methods

To pursue a previous in vitro evaluation, this in vivo 12 months prospective study followed up and compared the access-hole filling integrity of a modified 4-META (4-methacryloxyethyl trimellitate anhydride)/MMA-TBB (methyl methacrylate-tri-n-butyl borane) – based resin (M4M) and a photo-polymerizing nano-hybrid composite resin (CR).
Twenty-eight access-holes were filled with both materials respectively, then impressions and intra-oral photographs were taken at T = 0, T = 1 M (month), 3, 6, and 12 M. The access-hole surface measurement and the margin analysis (depth and angle) were carried out. The VAS (visual analogue scale) value on marginal discoloration and integrity at the baseline T = 0 and T = 12 M was recorded.

Results

The mean values of the surface areas changes from T = 1 to T = 12 M were 83.3 ± 11.5% for group CR and 77.1 ± 13.1% for group M4M, respectively. (Mann-Whitney test p < 0.05, p = 0.046). The mean marginal depth at T = 12 M for group CR were 141.2 ± 125.5 μm and 132.1 ± 107.8 μm for the group M4M, respectively. (Mann-Whitney test p > 0.05, p = 0.58). The mean values of the angle formed at the margin (T = 12 M) were for group CR 39.5 ± 19.4° and 28.2 ± 17.2° for group M4M, respectively (Mann-Whitney test p < 0.0001). The photographical analysis by VAS values showed no significant difference between CR and M4M groups (Mann-Whitney test p > 0.05, p = 0.848).

Conclusions

Based on intra- and extra-oral evaluations with the limitation, both CR and M4M combined with a ceramic primer are indicated as promising materials to fill the access-hole. Further long-term investigation is necessary to confirm this finding.

OraCoat® XyliGel® Assists Brace Wearers in Maintaining Good Oral Hygiene


Non-Acidic Soothing Gel Reduces New Plaque Buildup in Patients with Braces

Bellevue, WA (May 23, 2017) – OraCoat® XyliGel® helps reduce plaque and new cavities in brace wearers experiencing food and plaque buildup. The soothing gel acts as a buffer to neutralize harmful acids and works synergistically with a regular cleaning regimen to help preserve good oral hygiene while a patient wears braces.

Brace patients often face the development of tooth decay as a result of food and plaque forming between their brackets and wires. Although brushing and flossing are recommended to combat this issue, food particles may continue to linger, increasing the likelihood of new cavities.
By applying XyliGel between the brackets daily, brace wearers can help prevent new cavities. XyliGel helps to neutralize acids in the mouth with a pH of 7.4 and coats the mouth with xylitol to reduce new plaque formation. “For brace wearers, XyliGel is the perfect complement to regular cleaning,” stated Jeff Haley, OraHealth Corporation Founder, President, and Chief Scientist. “Consistent brushing and flossing after meals can eliminate some buildup; however, regular application of XyliGel greatly aids brace wearers in maintaining good oral hygiene.”

Effective for both daytime and nighttime use, XyliGel increases saliva production and coats the mouth and lips to help relieve dry mouth and reduce new plaque formation. The gel reduces plaque and acidity in the mouth.* XyliGel is the newest member of the OraCoat brand family of products which includes its flagship product, XyliMelts® oral adhering discs for dry mouth.

To order or obtain samples of XyliGel and for additional information on other OraCoat products, please visit www.oracoat.com.

Tooth discoloration effects of calcium silicate based barrier materials used in revascularization and treatment with internal bleaching


Abstract

Background/purpose

Usage of barrier materials is an important step in revascularization procedure. One of the undesired properties of these barrier materials is to cause coronal tooth discoloration. The aim of this in vitro study was to evaluate the tooth discoloration induced by ProRoot MTA (PMTA), Biodentine, and MM-MTA, as well as the efficacy of internal bleaching on this discoloration.

Materials and methods

Forty-two maxillary incisor teeth were prepared. Triple antibiotic paste (TAP) was placed in the root canals and incubated for 3 weeks. After removing the TAP, blood embedded spongostans were inserted into the root canals, and PMTA, Biodentine, or MM-MTA was placed over them. The teeth were incubated for 4 weeks at 37 °C; then, the internal bleaching agent was sealed for one week. The tooth color was measured throughout the study and the color change values (ΔE) of each specimen were calculated, and the data was statistically analyzed using the one-way ANOVA and Tamhane's T2 tests.

Results

The TAP significantly decreased the luminosity of the teeth (p < 0.05); however, no significant differences were observed between the tooth discolorations induced by the PMTA, Biodentine, and MM-MTA (p > 0.05). The teeth in the Biodentine group were more whitened than those of the PMTA and MM-MTA groups (p < 0.05).

Conclusion

Although the PMTA, Biodentine, and MM-MTA caused similar color alterations in the teeth, more bleaching was observed on those teeth discolored using TAP + blood + Biodentine.

Influence of cement type and ceramic primer on retention of polymer-infiltrated ceramic crowns to a one-piece zirconia implant


Abstract


Statement of problem

The best procedure for cementing a restoration to zirconia implants has not yet been established.

Purpose

The purpose of this in vitro study was to measure the retention of polymer-infiltrated ceramic crowns to zirconia 1-piece implants using a wide range of cements. The effect of ceramic primer treatment on the retention force was also recorded. The retention results were correlated with the shear bond strength of the cement to zirconia and the indirect tensile strength of the cements to better understand the retention mechanism.

Material and methods

The retention test was performed using 100 polymer-infiltrated ceramic crowns (Vita Enamic) and zirconia implants (ceramic.implant CI) The crowns were cemented with either temporary cement (Harvard Implant semipermanent, Temp Bond), glass-ionomer cement (Ketac Cem), self-adhesive cement (Perma Cem 2.0, RelyX Unicem Automix 2, Panavia SA), or adhesive cement (Multilink Implant, Multilink Automix, Vita Adiva F-Cem, RelyX Ultimate, Panavia F 2.0, Panavia V5 or Panavia 21) (n=5). Additionally ceramic primer was applied on the intaglio crown surface and implant abutment before cementation for all adhesive cements (Multilink Implant, Multilink Automix: Monobond plus; RelyX Ultimate Scotchbond Universal; Vita Adiva F-Cem: Vita Adiva Zr-Prime; Panavia F2.0, Panavia V5: Clearfil Ceramic Primer) and 1 self-adhesive cement containing 10-methacryloyloxydecyl dihydrogen phosphate (MDP) (Panavia SA: Clearfil Ceramic Primer). Crown debond fracture patterns were recorded. Shear bond strength was determined for the respective cement groups to polished zirconia (n=6). The diametral tensile strength of the cements was measured (n=10). Statistical analysis was performed using 1-way or 2-way analysis of variance followed by the Fisher LSD test (α=.05) within each test parameter.

Results

Adhesive and self-adhesive resin cements had shear bond strength values of 0.0 to 5.3 MPa and revealed similar retention forces. Cements containing MDP demonstrated shear bond strength values above 5.3 MPa and displayed increased retention. The highest retention values were recorded for Panavia F 2.0 (318 ±28 N) and Panavia 21 (605 ±82 N). All other adhesive and self-adhesive resin cements attained retention values between 222 ±16 N (Multilink Automix) and 270 ±26 N (Panavia SA), which were significantly higher (P<.05) than glass-ionomer (Ketac Cem: 196 ±34 N) or temporary cement (Harvard Implant semipermanent: 43 ±6 N, Temp Bond: 127 ±13 N). Application of manufacturer-specific ceramic primer increased crown retention significantly only for Panavia SA.

Conclusions

Products containing MDP provided a high chemical bond to zirconia. Self-adhesive and adhesive resin cements with low chemical bonding capabilities to zirconia provided retention force values within a small range (220 to 290 N).

Cetylite® Launches New Cool Mint Flavor of Cetacaine® Topical Anesthetic Gel



Pennsauken, NJ (May 15, 2017) — Cetylite® Inc. recently designed a new flavor of one of its flagship products, Cetacaine® Topical Anesthetic Gel. Cetacaine will now feature a Cool Mint flavored gel, which will be available by mid-June. Indicated for anesthesia of accessible mucous membranes (except the eyes), Cetacaine is primarily used to control pain and ease discomfort at the application site.

Cetacaine comes available in three forms; liquid, spray, and gel. The liquid form is applied subgingivally into periodontal pockets, where the viscous drops are easily dispensed using the soft-tipped syringe. The spray form safely dispenses a mist of Cetacaine through the spray cannula to suppress the gag reflex when taking x-rays or impressions. Both the liquid and spray are banana flavored. The gel form, which currently comes in a strawberry flavor, is applied with a cotton swab or micro brush to the site where pain control is needed prior to injection and treatment. Cetacaine Gel reacts with body temperature to melt and absorb quickly into tissue, and distributes evenly and consistently.

“When it comes to products that are used in the operatory, it’s all about trust,” stated Kathy Perini, Marketing Manager of Cetylite. “When a clinician finds a product that they can rely upon and that allows their patients to be comfortable, they recognize the value and become very loyal. We know this because dentists and hygienists tell us their success stories all the time. We are proud to have earned their trust. Cetylite has been able to stand tall all these years by making products that stand the test of time.”

The triple-active formula of Cetacaine (Benzocaine, 14.0%, Butamben 2.0%, and Tetracaine HCL 2.0%) features a rapid onset of less than a minute, and 30-60 minute duration. While many clinicians assume
Cetacaine is comparable to OTC 20% Benzocaine, a blind study published in the peer reviewed publication, Anesthesiology Review, shows the Cetacaine formulation to be more effective than
Benzocaine alone.* Cetacaine Gel offers an outstanding choice for practices looking for an alternative to Benzocaine-only formulations. 

Cetacaine is a prescription topical, for professional use only. It is available through most dental and medical suppliers. For more information about Cetacaine and other Cetylite products and services, please visit www.cetylite.com.

Dental Hygiene KOL Patti DiGangi, RDH Publishes the ROMA* Manual on Dentistry



Part of the DentalCodeology Series, the New Book is a Light Hearted,
Yet Deadly Serious Look at the Dental Profession

Addison, IL – May 09, 2017 – Patti DiGangi, RDH, BS, a prominent dental hygiene thought leader, took a totally different approach when writing the latest book in her DentalCodeology Series.

She and co-author Dr. Benson Baty took a humorous approach in examining some of the observations, insights and urban legends associated with patient communications, dental team interactions and clinical practice.

“You can’t make this stuff up,” says DiGangi. “I think everyone who has worked a few years in a dental office has a ROMA book in them!” If you think ROMA stands for Results Oriented Management and Accountability, think again. Those with a military background may recognize that ROMA is an acronym for “Right Outta My A_ _.”  

According to Dr. Baty, “Although we don’t want to be politically correct, we don’t want to offend either. If you are offended after learning what ROMA means, this may not be the book for you.”
The authors say the purpose of this book is to take a light-hearted view of dentistry while also challenging assumptions, questioning traditions and looking at the evidence with some ethical lessons thrown in for good measure.

For example, here’s a preview of some of the chapter topics:

·       Patients Say the Darndest Things
·       Professionals say the Darndest Things
·       Dental Education’s Darndest Things
·       Dentistry’s Darndest F-Words

The ROMA Manual of Dentistry is not intended to be a one-hit wonder. In fact, the authors believe there is a bottomless well of material to draw from. “Everyone working in dentistry has their own observations, insights and opinions,” explains DiGangi. We are planning to use a crowd-sourcing approach to gather some of the material for our next installment. Dental professionals will be provided opportunities to contribute on DentalCodeology.com and on our social media platforms.”

You can order your copy of The ROMA Manual: A Light Hearted, Yet Deadly Serious Look at Our Profession by clicking http://bit.ly/2pJgiC2.

About the Authors:

Patti DiGangi, RDH, BS is an international speaker who is passionate about prevention and working with dental professionals to improve practice profitability. Patti is the author of the recently-published book A Gingivitis Code Finally! - The fifth installment in the DentalCodeology series of bite-size books for busy dental professionals. Patti holds publishing and speaking licenses with the American Dental Association for Current Dental Terminology and SNODENT Diagnostic Coding and recently authored a chapter in the American Dental Association’s CDT 2017 Companion entitled “D9000 – D9999 Adjunctive General Services.” She is a proud member of the National Speakers Association.

Benson Blaty, DMD received his B.S. degree (Zoology) from Arizo­na State University (1979) and his DMD in 1983. He has been on the staff of Tulsa Community College Den­tal Hygiene Program for nearly a quarter of a century. Dr. Baty has maintained a full-time General Dentist­ry practice in Tulsa, OK since 1988. He has long felt that there is some humor to be found in many of the stressful events we face in our profession daily. Coping with those stresses is easier if some sort of humor can be extracted from the situation. Many times, a lesson can also be learned at the same time.

Properties of NeoMTA Plus and MTA Plus cements for endodontics

 

  • Accepted manuscript online:
  • DOI: 10.1111/iej.12787 

Abstract

Aim

To test a novel calcium silicate cement mixed with a water-based gel (NoeMTA Plus) with regards to chemical-physical properties and apatite forming ability.

Methodology

NeoMTA Plus (Avalon Biomed Inc. Bradenton, FL, USA; lot. 2014090301), and a commercial MTA-based material with similar properties (MTA Plus, Prevest Denpro Limited, Jammu, India; lot. 41001) were tested for ion-releasing ability, initial and final setting times, radiopacity, open and impervious porosity and apparent porosity, water sorption, weight loss, solubility, ability to nucleate calcium phosphates (CaP) after immersion in HBSS (Hank's Balance Salt Solution) by ESEM-EDX and Micro-Raman spectroscopy. The results were analyzed statistically with ANOVA test (P < 0.05).

Results

NeoMTA Plus had a prolonged setting time (315 min) and a satisfactory radiopacity (3.76 mm AL). Calcium and hydroxyl ion release was significantly greater and more prolonged in comparison with MTA Plus (P<0 .05="" ability="" after="" and="" both="" calcium="" confirmed="" esem-edx="" had="" hbss.="" high="" immersion="" in="" micro-raman="" mta="" neomta="" nucleate="" of="" on="" open="" p="" phosphates="" plus="" porosity="" solubility.="" surface="" the="" their="" to="" values="">

Conclusion

NeoMTA Plus is a new calcium silicate based cement for root filling with an adequate radiopacity and prolonged setting time. The ion release and CaP forming ability could increase stability of the root filling and promote endodontic and periodontal tissue regeneration, enhancing the bioactivity and biocompatibility of the material.

May 2017—With the comprehensive Dentsply Sirona Implants solutions portfolio, dental professionals can rest assured that they have the support they need for the full implant treatment process to restore function, esthetics and confidence to their patients.

The implant treatment process contains many steps—from imaging and diagnosis, treatment planning and implant surgery to abutment selection, restorative solutions and patient follow-up. Dentsply Sirona Implants presents several new solutions to their already extensive portfolio to delegates at their second World Summit Tour stop in San Diego.
“Whether thought leader, researcher, educator, Specialist, GP, or laboratory technician—while there are obvious unique differences and needs to be recognized, there is also a resounding commonality in the ease, precision, quality, speed and peace of mind that most dental professionals look for—ultimately for the benefit of the patients they serve,” says John Voskuil, VP and General Manager, Dentsply Sirona Implants, NA. “This is why we are committed to putting our customers first and to providing comprehensive end-to-end solutions that drive better, safer and faster dental care. It is exciting to be a part of an organization that can deliver on that promise and to be able to make a positive impact on the quality of life of others.”

Implant solutions

SmartFix® concept
SmartFix is a treatment concept that can provide edentulous patients with an immediate fixed, full-arch prosthesis, supported by a minimum four implants. The SmartFix concept includes an angulated abutment that comes together with a short and flexible abutment holder for easier handling. The option of angulating the screw access channel through the prosthesis opens up for ideal esthetics and function.
This concept is an easy and cost-effective treatment that offers improved treatment satisfaction for the patient and practice growth for the dental professional.
“The SmartFix concept has streamlined the treatment of my edentulous patients desiring a fixed prosthesis,” says Dr. Gary Jones, Board Certified Oral Surgeon in Fayetteville, NC. “The integrity of the balance base abutment-implant connection and its versatility with positioning, provide for a more efficient surgical procedure. My patients are overwhelmed with this life-changing, predictable treatment.”
SmartFix concept is now available for the Astra Tech Implant System EV product line in the US. Unique features include a holder made of Peek plastic for easier handling, especially in the posterior, and compatibility with the OsseoSpeed Profile EV, which when placed at an angle in the posterior, can further eliminate the need for bone reaming procedures. Multibase EV abutments are compatible with Nobel Biocare Multi-unit prosthetic cylinders and bridge screws. SmartFix concept is already available for Xive and Ankylos implant systems.
OsseoSpeed® Profile implants (Astra Tech Implant System)
Almost 40% of all implant sites present with a sloped alveolar ridge after healing.* The OsseoSpeed Profile EV implant (Astra Tech Implant System) is a uniquely shaped, patented implant specifically designed for just this clinical situation. It is designed to follow the natural shape of the bone, supporting the soft tissue by preserving marginal bone 360 degrees around the implant. In addition, it can help to eliminate the need for bone augmentation procedures. In fact, a reported 58% of all sloped implant sites have a reduced need for augmentation when using the OsseoSpeed Profile implant.
Dr. David Barack, a Periodontist from Skokie, IL states, “Since 1987, I have experienced the joys and frustrations of evolving implant technologies. The OsseoSpeed Profile EV implant has been one of the most impactful developments in my practice. I now place implants with optimal bone utilization, prevention of marginal bone loss, and position to neighboring teeth.”
Newly published results** on OsseoSpeed Profile implants show bone preservation, increased soft tissue volume and regain of keratinized mucosa in patients with compromised soft tissue conditions.
PD Dr. Robert Nölken, co-author of the study, explains “We have seen a great deal of improvement on the peri-implant soft tissue in our research follow-up. This allows us to achieve a good esthetic outcome for patients with thin biotypes.”
This prospective, 2-year follow-up, multicenter study—investigates OsseoSpeed Profile EV implant survival rate, soft and hard tissue maintenance following placement in healed sites of the posterior mandible. Twenty-four centers, 184 patients and 238 implants are included in the study.

Digital implant solutions

Atlantis® CustomBase solution
The Atlantis CustomBase solution combines an Atlantis Abutment and an Atlantis Crown with a screw access hole. The crown is cemented to the abutment extra orally and then all is screw-retained into the implant, avoiding potential complications caused by excess cement. The crown can be designed in the customer’s own software by ordering a unique digital file, with the screw hole indicated.
“Atlantis CustomBase gives our laboratory the ability to fabricate a screw-retained restoration with a custom designed titanium sub-structure,” states Conrad Rensberg, Owner and Head of Dental Implants, Absolute Dental Services, North Carolina. “Incorporating Atlantis CustomBase has greatly reduced post-delivery de-bonding and fracturing between the restoration and interface. The Atlantis CustomBase in gold-shaded titanium allows for brilliant color reproduction in our high translucent materials,”
Since the Virtual Atlantis Design (VAD) software takes the edentulous space with surrounding teeth and soft tissue anatomy into consideration, the Atlantis CustomBase solution is a premium, single-tooth, screw-retained solution providing patient-specific design of core height and optimized retention and design. This provides a result that replicates natural tooth function and esthetics. Moreover, the Atlantis CustomBase solution provides customized emergence profile for enhanced soft-tissue management and placement of material junction considering biological principles.
Prosthodontist, Dr. Mark Montana, Tempe, AZ, shares his clinical perspective. “Atlantis CustomBase provides customized emergence profile and optimal design of the axial walls, resulting in a restoration that is specific to a patient’s tissue and with a reliable cement interface, when compared to stock Ti-base alternatives.”
The Atlantis CustomBase solution is available for all major implant systems and is fully FDA compliant.
