ABSTRACT
In case of the insufficient horizontal bone loss, a regular diameter implant is not possible without lateral bone augmentation. In this situation, narrow diameter implants (NDIs) could be the alternative to lateral bone augmentation procedures. However, complication generally expected with the NDI is implant fracture. Recently, the survival rate and success rate of NDI in the posterior region are similar to that of standard-diameter implants (SDIs). These 3 case reports demonstrate the incorporation of NDI to replace missing mandibular posterior teeth. So far, the follow-up examination period was maintained and no unusual complications were presented for more than four years. Long term follow-up clinical data are needed to confirm the excellent clinical performance of these implants.

BACKGROUND: The objective of this retrospective study was to show results from platform-switched narrow-diameter implants in the posterior edentulous region, which we followed up for more than 1 year after functional loading. METHODS: Ninety-eight narrow implants were inserted into 66 patients. After healing, fixed implant-supported prostheses were delivered to the patients, and Periotest and radiographic examinations were performed. After the first year of loading, the implant outcome was again evaluated clinically and radiographically using the Periotest analysis. Crestal bone loss and Periotest values (PTVs) were used to evaluate the effect of surgery, prosthesis, implant, and a host-related factor. A general linear model was used to statistically detect variables statistically associated with crestal bone loss and Periotest value. RESULTS: We followed up on the implants over 1 to 4 years after loading; their survival rate was 100%, and pronounced differences from PTVs were noted among jaw location, bone quality, and loading period. No difference was detected in bone loss among the variables studied. Bone loss after functional loading was 0.14 ± 0.39 mm. The stability value from the Periotest was −3.29 ± 0.50. CONCLUSIONS: Within the limitations of this study, judicious use of platform-switched narrow implants with a conical connection must be considered an alternative for wide-diameter implants to restore a posterior edentulous region.

A descrição de técnicas de instalação de implantes e carga imediata tem lugar de destaque na literatura científica. A aplicação de carga imediata segue um protocolo rigoroso de trabalho e uma indicação precisa. Este trabalho teve como objetivo demonstrar um caso clínico onde foi utilizada a carga imediata para tratamento da agenesia do elemento 12 utilizando implante de plataforma estreita e técnica transgengival, sem abertura de retalho.
Implant placement techniques such as immediate loading protocols have received considerable attention on the scientific literature. However, immediate loading follows a strict protocol and precise indications. This paper presents a case report where agenesis at the maxillary right lateral incisor (12) was managed by using a narrow diameter implant with a flapless technique approach.
