Marginal Bone Level and Bone Thickness Reduction in Delayed and Immediate Implant Placement Protocol 6 Months Post-loading: An Observational Clinical Prospective Study.

Objectives: The aim of this prospective study was to assess marginal bone level (MBL), buccal and palatal bone thickness reduction (BTR) around implants in delayed and immediate placement protocols, 6 months after loading.

Materials And Methods: Twenty-four patients were assigned to two treatment groups, and treated with an immediate (Test) or delayed implant placement (Control). Baseline and 6 months post-loading periapical and Cone Beam Computed Tomography radiographs were used to measure mesial, distal, buccal, and palatal MBL change, and buccal and palatal BTR.

A Multidisciplinary Approach for the Management of Iatrogenic Severe Periodontitis Following Orthodontic Treatment with a 12-Year Follow-up.

Orthodontic treatment aims to realign teeth in a functional and esthetic manner. When applied on an unhealthy periodontium, this may lead to advanced periodontal tissue breakdown. The present 12-year follow-up report describes the multidisciplinary management of a severe, iatrogenic, generalized periodontitis case that was caused/aggravated by orthodontic therapy on unhealthy periodontal tissues.

Effect of Primary Stability and Soft- and Hard-Tissue Thickness on Marginal Bone Loss: A Prospective Pilot Study.

Objective: To compare prospectively the effect of different insertion torques (ITs) on marginal bone stability and study the effect of soft-tissue and buccal bone thickness as confounding factors while using a 3-dimensional radiographic evaluation.

Materials And Methods: Thirty-nine implants were placed in 22 patients. IT, soft-tissue thickness, and buccal bone thickness were recorded at implant placement.

Bone Lid Technique Using a Piezoelectric Device for the Treatment of a Mandibular Bony Lesion.

Different techniques for the enucleation of jaw cyst lesion in the oral and maxillofacial regions have been proposed, including the bone lid technique. The purpose of this case report is to describe the case of a cystic lesion, approached with the bone lid technique performed using a piezoelectric device, with an 8-month clinical and radiographic follow-up. A 14-year-old male patient was treated for a suspicious lesion detected on a panoramic radiograph.

Micromovement Evaluation of Original and Compatible Abutments at the Implant-abutment Interface.

Introduction: Use of compatible abutments may increase micromovements between the abutments, and the inner part of the implant may increase the stress on marginal bone level. Also micromovement will change the volume of the inner space of the implant-abutment complex. The resulting pumping effect can transport even initially immobile microorganisms from the exterior to the interior and vice versa.

Resonance frequency analysis, insertion torque, and bone to implant contact of 4 implant surfaces: comparison and correlation study in sheep.

Introduction: Primary stability is evaluated using resonance frequency analysis (RFA) and insertion torque (IT). Although there is a strong correlation between RFA and IT, studies failed to find a correlation between RFA and bone to implant contact (BIC) or IT and BIC.

Objective: To compare RFA, IT, and BIC of SLA, SLActive, Euroteknika, and TiUnite implant surfaces and evaluate the correlation between them.

Physicochemical characteristics of bone substitutes used in oral surgery in comparison to autogenous bone.

Bone substitutes used in oral surgery include allografts, xenografts, and synthetic materials that are frequently used to compensate bone loss or to reinforce repaired bone, but little is currently known about their physicochemical characteristics. The aim of this study was to evaluate a number of physical and chemical properties in a variety of granulated mineral-based biomaterials used in dentistry and to compare them with those of autogenous bone. Autogenous bone and eight commercial biomaterials of human, bovine, and synthetic origins were studied by high-resolution X-ray diffraction, atomic absorption spectrometry, and laser diffraction to determine their chemical composition, calcium release concentration, crystallinity, and granulation size.
