Aim: To compare surgically induced astigmatism (SIA) following horizontal rectus muscle recession surgery between suspension recession with both the "hang-back" technique and conventional recession technique.
Methods: Totally, 48 eyes of 24 patients who had undergone horizontal rectus muscle recession surgery were reviewed retrospectively. The patients were divided into two groups. Twelve patients were operated on by the hang-back technique (Group 1), and 12 by the conventional recession technique (Group 2). SIA was calculated on the 1(st) wk, 1(st) and in the 3(rd) mo after surgery using the SIA calculator.
Results: SIA was statistically higher in the Group 1 all postoperative follow-up. SIA was the highest in the 1(st) wk, and decreased gradually in both groups.
Conclusion: The suspension recession technique induced much more SIA than the conventional recession technique. This difference also continued in the following visits. Therefore, the refractive power should be checked postoperatively in order to avoid refractive amblyopia. Conventional recession surgery should be the preferred method so as to minimize the postoperative refractive changes in patients with amblyopia.

Methods for 3D evaluation and quantification of gingival recessions and gingival margin changes: Advancements from conventional techniques.

In an era of increasing life expectancy and growing patient demands towards lifelong natural tooth retention, accurate assessment of gingival recessions is crucial for diagnosing periodontal diseases, planning preventive or restorative interventions, and evaluating their outcomes. The traditional two-dimensional (2D) methods, while useful, often fall short in capturing the complex topography of gingival tissue margins and their changes over time. By examining relevant published studies, this review highlights the transition from 2D to 3D techniques, analyzing the limitations of widely used 2D approaches, while emphasizing the potential of novel 3D tools and techniques.

Objectives: This retrospective study aimed to evaluate the clinical outcomes associated with zygomatic implant (ZI) rehabilitation in partially atrophic edentulous maxillae over a mean follow-up period of more than 10.3 years.
Methods: All consecutive patients underwent ZI rehabilitation between 1999 and 2020, with a minimum follow-up period of 3 years.

Background: Platelet concentrates have gained significant attention in periodontology due to their regenerative properties. This randomized clinical trial was aimed to compare the clinical efficacy of advanced platelet-rich fibrin (A-PRF) and connective tissue graft (CTG) in the management of recession defects. The objectives were to compare changes in recession height and root coverage percentage between the groups.

Objective: Immediate Tooth Replacement Therapy (ITRT) has become popular due to its ability to reduce treatment time and provide immediate esthetic results. However, long-term challenges, such as mid-facial recession and labial bone resorption, have been reported. Anatomic temporary cylinders (ATC), which allow for efficient fabrication of provisional transitional restorations in the esthetic zone, were designed to mimic the natural emergence profile and guide mucosal tissue healing.

Article Synopsis
- The study investigates how platelet-rich plasma (PRP) injections affect periodontal health during accelerated orthodontic tooth movement (OTM) compared to traditional methods.
- 40 participants were randomly assigned to either a PRP-injected treatment group or a control group to analyze clinical and biochemical periodontal parameters over a 12-week period.
- Results showed no significant differences in periodontal health indicators or salivary enzyme levels between the two groups, indicating that PRP does not provide notable benefits in orthodontic treatment outcomes.
