Abstract
BackgroundShort implants (< 10 mm) are one of the treatment options available in cases of limited vertical bone. A purpose of this paper is to evaluate the predictability of short implants as an alternative to technically molthough such implants are now widely used, there is controversy regarding their clinical reliability. There complex treatments in patients with atrophic maxillae, based on a systematic review of the literature and the analysis of the implant survival rates, changes in peri-implant bone level, and associated complications. It is postulated that short implants offer clinical results similar to those of longer implants.Material and MethodsA Medline-PubMed search was made covering the period between January 2004 and December 2014 (both included). Studies in English published in indexed journals, involving at least 20 implants and with a follow-up period of at least 12 months were considered. A manual search in four high impact journals was also conducted.ResultsA total of 37 studies meeting the inclusion criteria were included in this review. 9792 implants placed in over 5000 patients were analyzed.ConclusionsBased on the results of this review, short implants are seen to offer clinical results in terms of survival, bone loss and complications similar to those of longer implants.

Highlights
Bone resorption occurring after tooth loss in either the upper maxilla or the mandible can give rise to an atrophic alveolar crest
Some previous publications have found these short implants to offer clinical results comparable to those obtained with longer implants – the implant survival rates ranging between 92.3% according to Slotte et al (3) and 100% as published by Anitua et al (4) in the posterior region of the mandible, and between 94.6% according to Renouard & Nisand (5) and 100% as published by Taschieri et al (6) in the posterior region of the upper maxilla
This study points to prosthetic splinting as one of the main factors conditioning implant survival in the case of posterior regions rehabilitation procedures. - Purpose The aim of the present study is to evaluate the predictability of short implants as an alternative to technically more demanding treatments, based on a systematic review of the literature and the analysis of the implant survival rates, changes in peri-implant bone level, and complications associated to the use of dental implants under 10 mm in length
Summary
Bone resorption occurring after tooth loss in either the upper maxilla or the mandible can give rise to an atrophic alveolar crest In most such cases, a functional and esthetically satisfactory dental implant supported rehabilitation is not possible. In the upper maxilla the main anatomical limitation is caused by the pneumatization of the maxillary sinus, while in the mandible the mandibular canal is the structure that conditions the available bone height For this reason, posterior regions of both maxillae are good candidates for rehabilitation using short dental implants. - Purpose The aim of the present study is to evaluate the predictability of short implants as an alternative to technically more demanding treatments, based on a systematic review of the literature and the analysis of the implant survival rates, changes in peri-implant bone level, and complications associated to the use of dental implants under 10 mm in length. Conclusions: Based on the results of this review, short implants are seen to offer clinical results in terms of survival, bone loss and complications similar to those of longer implants
