The gold standard is to place a regular diameter implant (>3.7 mm) or a wide one to replace every missing molar. Unfortunately, due to horizontal bone resorption, this option is not possible without lateral bone augmentation. In this situation, narrow diameter implant (NDI < 3.5 mm) could be the alternative to lateral bone augmentation procedures. This paper presents a clinical study where NDIs were used for the replacement of missing molars. They were followed up to 11 years. Special considerations were observed and many parameters were evaluated. NDI could be used to replace missing molar in case of moderate horizontal bone resorption if strict guidelines are res...

Being in most cases asymptomatic, it is often detected incidentally during routine oral examination. This report presents the case of a 38-year-old male who consulted for mild burning sensation in his mouth while consuming acidic foods and liquids. Intraoral examination revealed bilateral reticular OLP on the buccal mucosa; diagnosis was confirmed histopathologically. Treatment with topical corticosteroid leaded to significant symptoms improvement. Yearly long-term follow-up was requested to observe the disease activity and to rule out any malignant transformation.

PURPOSE The purpose of this retrospective observational study was to evaluate the success and survival rates of NDIs restored with fixed prostheses in the posterior region (primary outcome) and analyze whether splinting multiple units (prosthesis design) affects the biological and mechanical complications (secondary outcome). MATERIAL AND METHODS Dental records from 2 private clinics were reviewed for NDIs in the posterior region installed between 2009 and 2018. Ninety study participants (58 women and 32 men) aged between 21 and 84 years (mean age 49.9 years) were recalled for the assessment of implant survival and success of 160 NDIs previously provided for partial posterior edentulism associated with moderate horizontal bone loss or reduced interradicular space (105 premolars and 55 molars). The implants were restored with metal-ceramic single crowns or splinted multiple-unit prostheses, either screw-retained or cemented on customized (n=100) or stock titanium abutments (n=60). Peri-implant probing depth (PPD), bleeding on probing (BOP), bone quality, type of edentulism, and patient satisfaction were scored. The chi-square test for independence and 2-sample Welch t test were performed for statistical analysis (α=.05). RESULTS The overall success rate was 89.37%. One implant had been removed 4 years after loading, another after 9 years, yielding a cumulative survival rate of 98.75%. Fourteen implants exhibited PPD > 5 mm. One implant and 1 abutment screw fractured, and 16 restorations demonstrated porcelain chipping. The chi-square test showed no significant relationship between prosthetic design and complications whether biological (P=.087) or mechanical (P=.805). Eighty-two percent of patients were satisfied with esthetics, 76% with function, 85% with total duration of treatment, and 90% with overall treatment cost. CONCLUSIONS Within the limitations of this retrospective study, NDIs may be considered a reliable option to replace posterior teeth. The prosthetic design had no significant impact on biological or mechanical complications.

A reduced buccolingual ridge dimension may not allow the placement of a standard-diameter implant without the risk of implant thread exposure. In such situations, lateral bone augmentation procedures can be performed that would allow a restorative-driven placement of standard-diameter implants. Conversely, the use of narrow-diameter implants (diameter ≤ 3.5mm) could be another predictable solution to avoid any invasive surgical management. The aim of this review is to analyze the survival rate of narrow-diameter implants as well as the effectiveness of different techniques for lateral bone augmentation in improving implant clinical outcomes.

The purpose of this systematic review was to assess the survival of NDIs and provide guidelines for their safe use. Electronic search of the English-language literature enriched by hand search to identify suitable publications was made. Only peer-reviewed clinical studies published from January 1990 through March 2014 were included. Seventeen studies with a total of 1644 implants met the inclusion criteria, with an observation period from 1 up to 12 years. The mean survival rate of 98.6% was reported. Technical and other complications were observed. Short-term clinical data suggest that NDIs may serve in the posterior jaw as an alternative to standard-diameter implants. However, certain clinical conditions must be observed to assure long-term success.
