Clinical outcomes of dental implants in patients with and without history of periodontitis: A 20‐year prospective study

Abstract

Aim: To present the 20-year clinical outcomes of tissue-level implants in partially edentulous patients previously treated for periodontitis and in periodontally healthy patients (PHP). Material and Methods:The original population consisted of 149 partially edentulous patients consecutively enrolled in a private specialist practice and divided into three groups: PHP, moderately periodontally compromised patients (mPCP) and severely PCP (sPCP). After successful completion of periodontal/implant therapy, patients were enrolled in an individualized supportive periodontal care (SPC) programme.Results: Eighty-four patients rehabilitated with 172 implants reached the 20-year examination. During the observation time, 12 implants were removed (i.e., 11 due to biological complications and 1 due to implant fracture), leading to an overall implant survival rate of 93% (i.e., 94.9% for PHP, 91.8% for mPCP and 93.1% for sPCP [p = .29]). At 20 years, PCP compliant with SPC did not present with significantly higher odds of implant loss compared with PHP compliant with SPC (p > .05). Conversely, PCP not compliant with SPC experienced implant loss with odds ratio of 14.59 (1.30-164.29, p = .03).Conclusions: Tissue-level implants, placed after comprehensive periodontal therapy and SPC, yield favourable long-term results. However, patients with a history of periodontitis and non-compliant with SPC are at higher risk of biological complications and implant loss.

A novel porcine dentin-derived bone graft material provides effective site stability for implant placement after tooth extraction: a randomized controlled clinical trial

“…The use of osseointegrated dental implants has become a standard for the prosthetic rehabilitation of fully and partially edentulous patients, providing excellent longterm functional and esthetic outcomes [1][2][3][4][5]. Where necessary, to optimize the repair of dental bone defects and to adequately support implants, a wide variety of bone graft materials have been developed and are available on the market [6].…”

Root-Analogue Implants compared to Forced Orthodontic Extrusion: A retrospective analysis of clinical, radiological and esthetic outcomes after restoration.

“…Regarding this decision, future prosthodontic treatment options to restore function and esthetics should be considered. For the restoration of single-tooth gaps, conventional treatment options such as xed dental prostheses (FDPs) [3][4][5], resin-bonded xed dental prostheses (RBFDPs) [6-8] and implant-retained restorations [3,[9][10][11][12][13] have been established in daily dental routine. Usually, at this clinical state, teeth have already been removed or are expected to be extracted.…”

Immediate Functional Loading with Full-Arch Fixed Implant-Retained Rehabilitation in Periodontal Patients: Clinical Study

“…A long-term clinical study conducted over 20 years, concerning dental implants in patients with and without a history of periodontitis, showed that implants, placed after periodontal treatment and supportive periodontal care, yield favorable long-term results. However, patients with a history of periodontitis and non-compliance with supportive periodontal care are at higher risk of biological complications and implant loss [ 21 ].…”
