A simple technique is presented to make a multipurpose duplicate of the patient's complete denture to plan and fabricate a mandibular implant-retained overdenture. This duplicate serves 3 different functions. It can be used as a radiographic guide, surgical template, and custom tray adapted to the patient's occlusion. Advantages of the technique described are twofold: it is cost effective and makes use of equipment and materials commonly found in dental practices. The use of a single guide allows the clinician to refer to the recorded prosthetic data at each step of implant treatment.

This prospective, observational cohort study compares the clinical and radiographic outcomes of the modified Weaver and Dunn (WD) technique with the newer, anatomical double-button plus tendon allograft technique (DB), and the suture anchor repair plus tendon allograft (SA). The study cohort includes 53 patients, who underwent surgery for acromioclavicular joint (ACJ) dislocation Rockwood type 3, 4 and 5. Patient-reported outcome scores and clinical results, including Disabilities of the Arm, Shoulder and Hand (DASH), the Subjective Shoulder Value (SSV), the Visual Analogue Scale (VAS) and the Constant score (CS) results as well as loss of reduction rates on plain radiographs were compared.

The purpose of this study was to evaluate the radiographic outcomes of distal chevron metatarsal osteotomy associated with lateral joint capsule split as only lateral soft tissue release in patients with symptomatic moderate and severe hallux valgus (HV) deformity. Ninety patients (103 feet) at our institution between January 2014 and December 2019 were included in the present retrospective study. Each patient was evaluated preoperatively and at final follow-up by means of weight bearing radiographs lateral and dorsoplantar views.

Background: Few studies reported the long-term clinical outcomes and joint degeneration of patients with chronic lateral ankle instability (CLAI) and small osteochondral lesions of the talus (OLTs) following simultaneous open modified Broström-Gould (MBG) surgery and arthroscopic bone marrow stimulation (BMS). The purpose of this study was to study the long-term results of patients after BMS and BMG surgery, and to further evaluate the potential effect of OLT size on postoperative results.

Methods: In this retrospective study, 110 CLAI patients were divided into 57 patients with OLTs (including 24 patients having combined small osteochondral lesions of the tibial plafond) receiving simultaneous BMS and MBG surgeries (BMS+MBG group), and 53 patients without OLTs receiving isolated open MBG surgery (MBG group).

Aim: To test a BiO-Optimizing Site Targeted (BOOST) approach to periodontal regeneration by the adjunctive use of locally delivered doxycycline (DOX) 2 weeks prior to minimally invasive surgery in terms of clinical and radiographic outcomes at 1 year.

Methods: For this randomized clinical trial, stage III/IV periodontitis patients presenting sites with intrabony defects and bleeding on probing (BoP+) after steps 1-2 of periodontal treatment were included. Sites were treated via subgingival instrumentation with or without a BOOST approach by local DOX.
