Background/Objectives: The aim of this retrospective study was to radiographically evaluate the endo-sinus bone gain (ESBG) following osseodensification procedures using CBCT and compare results more conventional sinus lifting techniques. Methods: A total 72 patients underwent crestal floor elevation were provided with 102 implants a sand-blasted acid-etched surface microthreads (Medentika® Microcone Implants, Hugelsheim, Germany). Patients divided into two groups; group (OD; n = 36)...

Background: Maxillary sinus lifting procedure enables clinicians to place implant‐supported prostheses even in cases with very limited vertical bone height of the maxillary sinus. The aim this study was evaluate implant success regard effects membrane perforations that occurred during surgery. Methods: group consisted 91 patients (29 females and 54 males) edentulous posterior maxilla. Implant placement combined surgery performed, 259 implants were inserted. Sinus detected 12 sites. After...

Simultaneous insertion of multiple implants may exhibit suboptimal positions, especially in edentulous jaws considered for a fixed restoration. The aim this study was to compare the incidence and confounding factors implant positioning errors related use freehand computer-aided treatment methods.A total 353 were placed 54 patients with at least one jaw using methods involving 16 mucosa- 12 bone-supported single- multiple-type stereolithographic surgical guides. At stage prosthesis delivery,...

The aim of this study was to analyze the marginal bone loss and survival implants in augmented sinus area via lateral window approach. effect membrane perforation as well splinting upper structure analyzed. Two hundred eighty-nine were placed areas with xenografts collagen membranes 101 patients. Clinical radiographic data obtained during recall visits. Marginal Bone Loss (MBL) Cumulative Survival Rate (CSR) evaluated. mean follow-up period 12.4 years (range: 12 182 months). During period,...

ABSTRACT Purpose: Deviations of implants that were placed by conventional computed tomography (CT)‐ or cone beam CT (CBCT)‐derived mucosa‐supported stereolithographic (SLA) surgical guides analyzed in this study. Materials and Methods: Eleven patients randomly scanned a multi‐slice (CT group) CBCT scanner (CBCT group). A total 108 planned on the software using SLA guides. new scan was obtained merged with planning data to identify deviations between implants. Results Mann‐Whitney U test...

Objectives: Chemical modification of the already proven sand-blasted and acid-etched (SLA) implant had increased its surface wettability consequent early-term osseointegration characteristics. The aim this clinical trial was to compare stability changes, success, survival, peri-implant parameters marginal bone loss (MBL) early-loaded standard modified sand-blasted, (modSLA) implants. Material methods: A total 96 SLA modSLA implants were placed in a bi-lateral, cross-arch position jaws 22...

Objective: The aim of this pilot study was to compare the early-term osseointegration characteristics standard (SLA) and modified sand-blasted acid-etched (modSLA) implants in an experimental animal model. Material methods: A total 30 SLA modSLA were placed tibiae three sheep insertion torque value (ITV) resonance frequency analysis (RFA) measurements performed. RFA measurement repeated on 3 6 weeks healed after which animals sacrificed for histomorphometric analysis. Bone-to-implant contact...

The absence of sufficient bone volume is the most relevant problem in implant dentistry. Grafting from exogenous sources may provide a limited gain but exhibits poor performance large defects. Autogenous block transfer (ABBT) mandibular symphysis and ramus has been used with varying rates success. aim this study was to compare efficacy symphysal ABBT for restoration lost horizontal alveolar anterior maxilla. Implants placed augmented areas were also evaluated.The maxillary deficits 32...

Restoration of the lost bone volume is one most deliberate issues in dentistry. Sustained-release microspherical oxytocin hormone a poloxamer hydrogel scaffold combined with mixture β-tricalcium phosphate and hydroxyapatite (CP) may serve as suitable graft.
