This review is from the same team that conducted the study we looked at yesterday (Dental Elf 28th Nov 2012) looking at treatments for edentulism. The aim of this review was to identify and critically appraise published studies of treatment methods used in general practice to rehabilitate adult patients with single tooth loss or partial edentulism, with special emphasis on outcomes reported after at least 5 years of follow-up.
PubMed, The Cochrane Central Registry of Controlled Trials, Embase, the National Health Service Economic Evaluation Database, and the Health Economic Evaluation Database were searched with no language limits. Reference lists of included publications were also searched. The literature was divided into two sections single tooth loss and partial edentulism. The review excluded studies of advanced patient cases, such as those in which limited bone volume for implantation required regenerative or augmentation procedures. The quality of evidence was classified according to the GRADE system.
- 15 studies (7 retrospective) were included (5 of moderate quality, 10 low-quality)
- The 5-year survival rates for implant-supported single crowns and prostheses were 91% and 94.7%, respectively (implant survival rates: 98.5% and 94.9%, respectively). The underlying scientific evidence was low in quality. No relevant publications were identified regarding the economic aspects of treatment.
The authors concluded
Due to the low scientific evidence of the included studies, it was not possible to compare various treatment methods used for rehabilitation of single tooth loss or partial edentulism.
