Narrow Diameter Implants

Abstract Background: Nowadays, narrow diameter implants are being increasingly used in posterior regions with insufficient bone width to avoid invasive bone augmentation procedures. Recent studies have indicated that narrow implants with a diameter of 3.3 to 3.5mm showed comparable survival rate with standard diameter implants. However, there are no high-quality clinical trials comparing the clinical outcomes of narrow diameter implants to standard diameter implants with augmentation procedures in atrophic posterior region. The purpose of present study is to evaluate the clinical efficacy of narrow diameter implants in posterior jaws. Methods/Design: This study is designed as a prospective, single-center, 2-arm parallel, randomized controlled clinical trial. Patients in need of single implant crowns in posterior jaws will be included in the study according to clear defined inclusion-and-exclusion criteria. Randomized number table will be used to assign the patients into two groups: group 1: narrow diameter implant group (NDI); group 2: standard diameter implant with bone augmentation group (SDI). Implant survival rate, mechanical complications, marginal bone loss, peri-implant conditions and patients’ satisfaction will be recorded. Clinical and radiological re-evaluations will be performed at 6, 12, 36, 60 months after the final crowns delivery. Discussion: Our findings will help evaluate the clinical efficacy of narrow implant in posterior region. If the results were favorable, narrow implants might be recommended as a viable alternative for posterior region with insufficient bone width.

The Mean

Aim of the study: This RCT assesses patients’ 18-month clinical outcomes after the regenerative therapy of periimplantitis lesions using either an electrolytic method (EC) to remove biofilms or a combination of powder spray and an electrolytic method (PEC). Materials and Methods: Twenty-four patients (24 implants) suffering from periimplantitis were randomly treated by EC or PEC followed by augmentation and submerged healing. Probing pocket depth (PPD), Bleeding on Probing (BoP), suppuration, and standardized radiographs were assessed before surgery (T0), 6 months after augmentation (T1), and 6 (T2) and 12 (T3) months after the replacement of the restoration. Results: The mean PPD changed from 5.8 ± 1.6 mm (T0) to 3.1 ± 1.4 mm (T3). While BoP and suppuration at T0 were 100%, BoP decreased at T2 to 36.8% and at T3 to 35.3%. Suppuration was found to be at a level of 10.6% at T2 and 11.8% at T3. The radiologic bone level measured from the implant shoulder to the first visible bone to the implant contact was 4.9 ± 1.9 mm at mesial sites and 4.4 ± 2.2 mm at distal sites at T0 and 1.7 ± 1.7 mm and 1.5 ± 17 mm at T3. Conclusions: Significant radiographic bone fill and the improvement of clinical parameters were demonstrated 18 months after therapy.
