Sequencing osteotomes to overcome challenges presented by deficient bone quantity and quality in potential implant sitesThe combination of inadequate bone volume, poor bone quality, and elevated occlusal forces contributes to the posterior maxilla being the least predictable site for implant survival. Osteotomes are surgical instruments that have been designed in an attempt to improve bone quantity and quality. Conflicting reports in the literature compare the percentages of bone-to-implant surface contact between the implants placed using osteotomes and conventional drills. However, some studies use different osteotomes that may be harmful to the bone. Innovative pilot intermediary osteotomes used in conjunction with divergent sequential osteotomes to ensure parallelism, expand narrow ridges predictably, safely and significantly internally elevate the sinus, aid in future site development, and assist in immediate implant placement are introduced. The hypothesis is that the quality of bone is simultaneously enhanced, but controlled clinical studies are needed to prove this theory.

The use of transitional implants to support provisional prostheses during the healing phase: A literature reviewObjective: Transitional implants are indicated for cases in which immediate loading is counterindicated because a healing period is necessary for osseointegration of the definitive implants. These provisional implants were developed to support an implant-supported fixed prosthesis or overdenture to provide retention, stability, and support. The aim of this article was to conduct a literature review on transitional implants to highlight the characteristics of the transitional implants and their advantages, indications, and contraindications, including the level of osseointegration of such implants according to the functional period.Method and Materials: The present literature review was based on the OldMedline and Medline databases from 1999 to 2010 using the key words “transitional implants" and “temporary implants." Fourteen articles were found: 11 clinical studies or techniques and three histologic and histomorphometric studies.Results: The transitional immediate prostheses were worn by completely and partially edentulous patients. Advantages of transitional implants include complete denture retention, stability, and support; maintenance of chewing, phonetics, and patient comfort; protection of bone grafts; vertical stop during healing period; easy and fast surgical and prosthetic procedures; lower cost in comparison to the definitive implant; and reestablishment of esthetics. The success of transitional implants as conservative treatment for conventional immediate loading is a reality if correctly indicated.Conclusion: Transitional implants are a provisional treatment alternative for completely and partially edentulous patients. However, additional studies are required to evaluate the level of remodeling and repair of the transitional implants under loading.

Surgical repositioning of the impacted immature maxillary central incisorSurgical repositioning is a treatment option for an impacted tooth with root dilaceration in an inverted position. In this case report, surgical repositioning of an abnormally impacted and labially dilacerated maxillary right central incisor is described. The impacted and dilacerated maxillary incisor was surgically repositioned in the early root development period and erupted into proper position with normal root development during a 2-year follow-up period.

The antiplaque efficacy of pomegranate mouthrinseObjective: To evaluate the effect of a pomegranate-containing mouthrinse on plaque, determine whether it has any adverse effects, and evaluate its antibacterial properties against selected periodontopathogens in vitro.Method and Materials: Thirty periodontally healthy volunteers, randomly divided into three groups, refrained from all mechanical oral hygiene measures for 4 days and used one of the randomly assigned mouthrinses (A, pomegranate; B, chlorhexidine; or C, distilled water [placebo]) twice daily. The Plaque Index (PI) was assessed at days 0 and 5. Adverse effects were also evaluated. Pomegranate extract was tested against Aggregatibacter actinomycetemcomitans (A.a.), Porphyromonas gingivalis (P.g.), and Prevotella intermedia (P.i.).Results: In all groups, the PI significantly increased from the baseline to day 5 (P < .1). The pomegranate mouthrinse created no adverse effects. There was a statistically significant difference (P < .05) between the chlorhexidine and placebo rinse and the pomegranate and placebo rinse, but no statistically significant difference was found between the chlorhexidine and pomegranate rinse with respect to the PI. Pomegranate extract showed inhibition of all three strains of periodontopathogens at various concentrations.Conclusion: These results indicate that the pomegranate mouthrinse has an antiplaque effect. Pomegranate extract is efficacious against A.a., P.g., and P.i. strains in vitro. Pomegranate mouthrinse should be explored as a long-term antiplaque rinse with prophylactic benefits.
