Abstract
This article reviews the literature on the outcome of flapless surgery for dental
implants in the posterior maxilla. The literature search was carried out in using
the keywords: flapless, dental implants and maxilla. A hand search and Medline search
were carried out on studies published between 1971 and 2011. The authors included
research involving a minimum of 15 dental implants with a follow-up period of 1 year,
an outcome measurement of implant survival, but excluded studies involving multiple
simultaneous interventions, and studies with missing data. The Cochrane approach for
cohort studies and Oxford Centre for Evidence-Based Medicine were applied. Of the
56 published papers selected, 14 papers on the flapless technique showed high overall
implant survival rates. The prospective studies yielded 97.01% (95% CI: 90.72–99.0)
while retrospective studies or case series illustrated 95.08% (95% CI: 91.0–97.93)
survival. The average of intraoperative complications was 6.55% using the flapless
procedure. The limited data obtained showed that flapless surgery in posterior maxilla
areas could be a viable and predictable treatment method for implant placement. Flapless
surgery tends to be more applicable in this area of the mouth. Further long-term clinical
controlled studies are needed.
