Purpose: The objective of this prospective randomized clinical trial (RCT) was to analyze and compare the clinical behavior of three types of prosthesis supported by single implants in the posterior region after three years of functional loading. Materials and methods: Seventy-five implants were divided into three groups according to the type of prosthetic restoration: screw-retained crown (group GS); cemented crown without finishing line (biologically oriented preparation technique) (group GBOPT); and conventional cemented crown with finishing line (group GCC). After three years in function, clinical parameters (presence of keratinized mucosa, probing depths, bleeding on probing, and radiographic bone loss) were compared between the three experimental groups. The possible correlation between soft tissue clinical parameters and bone loss was also analyzed. Results: Statistical analysis found significant differences in clinical parameters between the different types of crown, with the cemented restoration without finishing line (BOPT) presenting fewer complications and better peri-implant health outcomes including: significantly different KMW data (mm), with significant differences between groups GBOPT and GCC (p < 0.001, Kruskal–Wallis test), with GBOPT obtaining larger quantities of keratinized mucosa (KM); statistically significant differences in probing depth (PD) values between groups GBOPT and GCC (p = 0.010, Kruskal–Wallis test); significant differences in bleeding on probing (BOP) between groups GBOPT and GCC (p = 0.018, Chi2 test) in favor of GBOPT. Conclusions: Soft tissue behavior around implants is related to the type of prosthetic restoration used, with cemented prostheses with BOPT presenting better peri-implant soft tissue behavior.

Purpose: The objective of this prospective randomized clinical trial (RCT) was to analyze and compare the clinical behavior of three types of prosthesis supported by single implants in the posterior region after three years functional loading. Materials and Methods: Seventy-five implants were divided into three groups according to the type of prosthetic restoration: screw-retained crown (Group GS); cemented crown without finishing line (biologically oriented preparation technique) (Group GBOPT); and conventional cemented crown with finishing line (Group GCC). The clinical behavior of each restoration type was analyzed after 3 years functional loading by analyzing radiographic peri-implant bone loss. Results: GBOPT obtained the least bone loss (p < 0.01) in comparison with GS and GCC. Conclusions: Bone loss around implants is related to the type of prosthetic restoration it supports, whereby cemented BOPT crowns present less bone loss.

<p><strong>BACKGROUND &amp; AIM: </strong>Photodynamic therapy is a localized non-invasive treatment modality for the periodontal disease. Some evidences have shown that this technique is effective in improving the treatment outcome. This study compared the effects of photodynamic therapy with and without scaling and root planing and scaling and root planing alone on the clinical parameters of the chronic periodontitis.</p><p><strong>MATERIALS &amp; METHODS: </strong>In this single-blind, randomized clinical trial, 30 chronic periodontitis patients (10 for each modality) were selected and three different methods; photodynamic therapy alone (Group1) by FotoSan 630 system, scaling and root planning (SRP) alone (Group2), scaling and root planing combined with photodynamic therapy (Group3) were done for them randomly. Clinical parameters of probing pocket depth (PPD), bleeding on probing (BOP), and clinical attachment level (CAL) were measured at the baseline and 3, 6 and 12 weeks later. One-sided analysis of variance test was used to analyze PPD and CAL among the treatment groups in each time interval while the paired comparisons were carried out by employment of Dunnett’s test. The treatment groups were statically analyzed by the chi-square test regarding BOP. <strong></strong></p><p><strong>RESULTS: </strong>Before the treatment; no significant differences observed among treatment modalities regarding clinical parameters; while the differences were significant at three weeks (p&lt;0.0001 for PPD and CAL; p&lt;0.001 for BOP); six weeks (p&lt;0.0001 for PPD and CAL, p&lt;0.002 for BOP); and 12 weeks after the treatment (all: p&lt;0.0001). The least PPD and CAL values and the most frequency of non-bleeding on probing status were measured for PDT+SRP modality at three, six, and twelve weeks after the treatment.</p><p><strong>CONCLUSION: </strong>Photodynamic therapy supported the clinical parameters of periodontitis similar to SRP; however, PDT combined with SRP demonstrated a better result than that of SRP alone. Therefore, PDT combined with SRP can be used to improve outcomes of clinical parameters of periodontitis as compared to SRP alone in the short-term.</p>
