Single-Stage Lateral Sinus Floor Elevation Using Different Grafts: A Systematic Review of Controlled Clinical Trials.

Purpose: To assess histologic and imaging outcomes related to new bone formation around implants, inserted simultaneously with sinus augmentation, and compare different types of grafts.

Materials And Methods: This systematic review (SR) was carried out following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and the Cochrane Handbook for Systematic Reviews of Interventions. LILACS/BVS, MEDLINE/PubMed, Cochrane Library, and Embase databases, including gray literature and manual investigations, were searched to identify clinical trials reporting specific requirements.

Blood clot stability and bone formation following maxillary sinus membrane elevation and space maintenance by means of immediate implant placement in humans. A computed tomography study.

Objective: The present controlled clinical pilot study proposed to assess blood clot contraction and bone neo-formation following maxillary sinus lift (MSL) with immediate implant placement without using grafts using cone beam tomography exams.

Materials And Methods: Ten implants were placed in ten patients with a residual bone crest height ≥4 and ≤ 7 mm, in maxillary premolars or 1st or 2nd molars regions, using MSL and immediate implant placement without grafts, by means of the lateral window approach. A resorbable membrane (Bio-Gide®, Geistlich, USA) was used to close the window.

Assessment of Dental Implant Stability in Areas Previously Submitted to Maxillary Sinus Elevation.

This study aimed to compare the primary and secondary stability, measured by resonance frequency analysis (RFA), in implants of different lengths installed in areas submitted to maxillary sinus lift. Correlation between RFA and implant insertion torque was also assessed. Twenty implants of 9 and 11 mm were inserted in areas submitted to maxillary sinus lift.

Vertical augmentation of the posterior atrophic mandible by interpositional grafts in a split-mouth design: a human tomography evaluation pilot study.

Objective: Using computed tomography, to compare vertical and volumetric bone augmentation after interposition grafting with bovine bone mineral matrix (GEISTLICH BIO-OSS ) or hydroxyapatite/tricalcium phosphate (STRAUMANN BONECERAMIC) for atrophic posterior mandible reconstruction through segmental osteotomy.

Material And Methods: Seven patients received interposition grafts in the posterior mandible for implant rehabilitation. The computed tomography cone beam images were analysed with OsiriX Imaging Software 6.

Impact of human maxillary sinus volume on grafts dimensional changes used in maxillary sinus augmentation: a multislice tomographic study.

Purpose: To assess the influence of complete maxillary sinus volume on the dimensional changes of different grafts used in maxillary sinus lift.

Materials And Methods: Analysis of 50 surgical procedures of maxillary sinus lift performed on 43 subjects using different grafting materials: fresh frozen allogenic particulated bone (11), hydroxyapatite (Endobon(®)) (17), 60% hydroxyapatite + 40% beta-tricalcium phosphate (Bone Ceramic(®)) (12) and Bone Ceramic(®) + Emdogain(®) (10). One hundred and fifty multislice tomographic images of the maxillary sinus were obtained using the software Syngo CT 2011 A VOLUME, measuring complete maxillary sinus volume (T0) and dimensional changes of different graft materials during periods of 15 days (T1) and 180 days (T2).

Volumetric dimensional changes of autogenous bone and the mixture of hydroxyapatite and autogenous bone graft in humans maxillary sinus augmentation. A multislice tomographic study.

Purpose: This multislice tomographic study evaluated the dimensional changes after maxillary sinus augmentation using autogenous bone or a mixture of hydroxyapatite and autogenous bone.

Materials And Methods: Ten selected patients, requiring a bilateral maxillary sinus augmentation, were divided, in a split mouth, design as follows: control group (CG n = 10 sinus grafted with autogenous bone) and test group (TG, n = 10 sinus grafted with a mixture of hydroxyapatite and autogenous bone at 80 : 20 w/w). Follow a healing period of 15 and 180 days, computed tomography (CT) measurements were taken by two blinded and calibrated examiners to verify the volumetric dimensional changes of the both groups.

Mass retraction movement of the anterior upper teeth using orthodontic mini-implants as anchorage.

Background: Several studies have demonstrated the application of mini-implants in the orthodontic treatment as anchorage during the retraction movement of the anterior teeth.

Purpose: This study was designed to evaluate the mass retraction movement of the anterior upper teeth using orthodontic mini-implants as anchorage.

Materials And Methods: Nine patients with class I malocclusion and Angle's class II, needing extractions of the upper first premolars, were enrolled in this case series.
