Comparison of immediate‐load mini dental implants and conventional‐size dental implants to retain mandibular Kennedy class I removable partial dentures: A randomized clinical trial

First published: 31 July 2018

 

Abstract

Background

Complications of distal extension mandibular removable partial dentures are: loss of retention, irritation, and so forth. Dental implants have been used to support distal extension removable partial dentures. However, many patients have limited bone support in which to place conventional‐size dental implants.

Purpose

To compare the clinical outcomes of using immediate‐loaded mini dental implants and immediate‐loaded conventional‐size dental implants, when used to retain mandibular Kennedy class I removable partial dentures.

Materials and Methods

Thirty patients were randomly divided into two groups. Mini dental implants and conventional‐size dental implants were placed in participants in the first molar region on both sides. The dentures were connected immediately. Patients were recalled on 1, 3, 6, and 12 months after surgery. Digital periapical radiographs were made, and patient satisfaction was recorded. Data were analyzed by independent samples t‐test and paired samples t‐test (P = .05).

Results

Twenty eight of the implants survived (survival rate = 93.3%) in each group. Mean radiographic bone loss was 0.47 ± 0.42 and 1.03 ± 1.07 mm in groups 1 and 2, respectively. Conventional‐size implants revealed significantly greater marginal bone loss than mini implants (P = .01). Patient satisfaction showed significant improvement after treatment in both groups.

Conclusions

Immediate‐loaded mini dental implants can be applied for retaining mandibular Kennedy class I removable partial dentures with very favorable results.
