17. Case of the Month Guided Tissue Regeneration with Bone Grafting for Treatment of Peri-Implantitis Induced by Retained Cement By Ahmad Soolari
Treatment outcomes for implant dentistry are generally positive, but implants do occasionally fail. One cause of ailing and failing implants is retained subgingival cement. This case report documents treatment of an ailing implant due to retained cement following final crown cementation. A 37 year old Asian male presented to our office with a chief complaint of severe pain and gingival swelling around his implant supported crown at the mandibular right second molar. Both the patient and restorative doctor were very interested in saving the implant. Following administration of local anesthesia, flap reflection enabled observation of retained excess subgingival cement. Granulation tissue associated with subgingival cement was removed along with the cement. The contaminated dental implant surface was detoxified with chlorhexidine and rinsed with sterile saline. The peri-implant intrabony defect was grafted with freeze dried bone allogaft (Life Net Health, Virginia Beach, Virginia, USA) and guided tissue regeneration was achieved with a bioabsorbable collagen barrier (Geistlich Pharma NA, Princeton, New Jersey, USA). The surgical site then healed without further incident, and the pain was resolved. The nine month post treatment radiograph showed significant improvement of the peri-implant intrabony defect. This is a good example of TEAM dentistry where close cooperation between professionals enables delivery of outstanding dentistry.
21. Dental Implant Migration into Two Different Maxillary Sinus Cavities By Leon Chen, Jennifer Cha
The field of maxillary sinus augmentation and dental implant placement is expanding rapidly. A recently released American Dental Association (ADA) survey reveals a significant and consistent increase in the number of implants placed annually. Although numerous studies have shown the overall implant survival rate in the maxillary region to be over 91%, invasion of the maxillary sinus cavity is a frequent complication in dental implant treatment. The main contribution to this phenomenon is likely due to a simple increase in the number of implants placed. Yet, there is a paucity of reports in the literature of implants migrating into the sinus space. This case study presents two different types of invasion of the maxillary sinus by dental implants. These cases serve to remind specialists in dentistry that an aberrantly extruded implant can be occupied in two different spaces within the maxillary sinus cavity, and the necessity to differentiate and/or identify these two spaces.
27. Expansion of Atrophic Posterior Mandibular Ridge: A Case Report By Marcus J. Blue, Charles M. Cobb
Reduced function due to edentulation is related to skeletal change such as residual ridge resorption and loss of cortical bone thickness. Even with adequate cortical plate thickness, the ridge itself may present inadequate buccal-lingual dimensions, thereby requiring lateral expansion to facilitate successful dental implant placement.
39. Guided Bone Regeneration with Vicryl® Knitted Mesh: A Pictorial Description of the Technique By Barry Wagenberg
A variety of barrier membranes have been utilized over the years for guided bone regeneration. Each membrane type has its own unique set of advantages and disadvantages. Vicryl® mesh is an absorbable, synthetic barrier composed of polyglactin 910. When used for guided bone regeneration, this material demonstrates minimal absorption until 8 weeks after placement and is typically resorbed completely within 60 to 90 days. In this article, the author provides a concise review and pictorial description of the use of Vicryl® mesh for guided bone regeneration in the practice of surgical dentistry. The author has performed thousands of cases with this technique over the past 20 years.
49. Editorial Opinion on the Use of the Laser in Periodontal and Restorative Dentistry BY Daniel J. Melker, Donato Napoletano
Lasers, whether they are used to perform hard or soft tissue procedures, are rapidly becoming an integral part of dental practice. The authors of this editorial opinion would like to give an overview of their own personal recommended guidelines for the use of lasers in periodontal treatment, and more importantly, when they should not be used, particularly when extensive restorative treatment is required. Several case examples will be used to illustrate these points. These suggested guidelines are those of the authors and do not reflect any of the views or opinions regarding lasers by the Journal of Implant and Advanced Clinical Dentistry (JIACD), its editorial board, or anyone else associated with the journal. Counterpoints and alternative views are encouraged to be submitted by anyone that desires to do so.
