Four databases-PubMed, EMBASE, Cochrane Library, and China National Knowledge Infrastructure-were searched from their inception through December 2020. English and Chinese randomized controlled trials (RCTs) that compared minocycline hydrochloride with control regimes, including negative control, iodine solution or glycerin, and chlorhexidine, for patients with peri-implant diseases were retrieved. Three outcomes-plaque index (PLI), probing depth (PD), and sulcus bleeding index (SBI)-were assessed using meta-analysis based on the random-effects model. Fifteen RCTs were included in the present meta-analysis, and results suggested that minocycline hydrochloride significantly affected PLI, PD, or SBI reduction regardless of the type of comparator regime. However, subgroup analyses suggested that minocycline hydrochloride was not superior to chlorhexidine in terms of reduction of PLI (1 week: MD = -0.18, 95% CI = -0.55 to 0.20, P = .36; 4 weeks: MD = -0.08, 95% CI = -0.23 to 0.07, P = .28; 8 weeks: MD = -0.01, 95% CI = -0.18 to 0.16, P = .91) and PD (1 week: MD = 0.07, 95% CI = -0.27 to 0.41, P = .68; 4 weeks: MD = -0.10, 95% CI = -0.43 to 0.24, P = .58; 8 weeks: MD = -0.30, 95% CI = -0.68 to 0.08, P = .12), and minocycline hydrochloride was also not better than chlorhexidine regarding reduction of SBI at 1 week after treatment (MD = -0.10; 95% CI = -0.21 to 0.01; P = .08). This study concludes that minocycline hydrochloride as adjuvant therapy of nonsurgical treatment enhances the clinical results when compared to control regimes.

In this study, a new abutment-bar structure connection was introduced to minimize undesired bending moments and reduce the resulting stresses by increasing the rotational mobility of the bar structure on the abutments. Copings of the bar structure were modified to have 2 spherical surfaces, sharing the same center, located at the centroid of the top surface of the coping screw head. The new connection design was applied to a 4 implant-supported mandibular overdenture to create a modified overdenture. Both the classical and modified models had bar structures with cantilever extensions in the first and second molar areas and were analyzed for deformation and stress distribution using finite element analysis, which was also conducted for both the overdenture models without cantilever bar extensions. Real-scale prototypes of both models with cantilever extensions were manufactured, assembled on implants embedded in polyurethane blocks, and subjected to fatigue testing. Both models' implants were subjected to pullout testing. The new connection design increased the rotational mobility of the bar structure, minimized the bending moment effects, and reduced the stress levels in the peri-implant bone and overdenture components, whether cantilevered or not.

Changes in bone thickness and density (tomographic evaluation), levels of complications (clinically), and distribution pattern between mineralized and nonmineralized tissue (histomorphometrically) were analyzed. Tomographic analysis showed a horizontal bone increase of 4.25 ± 0.78 mm in the TG and 3.08 ± 0.8 mm in the CG between baseline and 8 months postoperatively (P < .05). The horizontal loss between the day of installation of the blocks and 8 months postoperatively was 1.02 ± 0.39 mm for the TG and 1.10 ± 0.71 mm for the CG (P > .05).
