Purpose. Computer-assisted stereolithographically guided surgery allows an ideal implant placement for prosthetic restoration. Two types of stereolithographic templates are currently available: a fully template and pilot-drill template. The purpose this study was (i) to evaluate the accuracy insertion using these surgical (ii) define parameters influencing accuracy. Materials Methods . 20 patients were enrolled divided into 2 groups: in group A, implants placed CAD-CAM with sleeves; B, only...

Thirty sites grafted collagenated cortico-cancellous (coll), 30 cortical (cort) porcine bone natural healing. Primary (vertical horizontal 3 months) secondary outcomes (histomorphometric evaluated at implant placement.The vertical sockets...

Abstract Background Guided bone regeneration (GBR) allows to achieve vertical ridge augmentation whether with nonresorbable membranes or resorbable Ti‐mesh, but till now no studies are published comparing histological and histomorphometrical outcomes of these two procedures. Materials Methods Forty partially edentulous patients required place implants in the posterior mandible: 20 were randomly assigned group A (Ti‐PTFE); while B (Collagen plus Ti‐mesh). For both groups, graft material was a...

The aim was to evaluate the role of resorbable membranes applied over customized titanium meshes related soft tissue healing and bone regeneration after vertical/horizontal augmentation.Thirty patients with partial edentulism maxilla/mandible, reabsorption alveolar bone, needing implant-supported restorations, were randomly divided into two groups: Group A treated using only custom-made (Mesh-) B cross-linked collagen (Mesh+). Data collection included surgical/technical complications,...

In the past 10 years, long-term studies have demonstrated that guided bone regeneration (GBR) is a successful and reliable technique for vertical horizontal ridge augmentation, but strict rigorous protocols must be adopted.Because no reports yet been published with statements clinical recommendations GBR, closed meeting of all authors was organized to discuss this matter during GBR symposium held in Bologna (Italy) October 2016. The focused on findings systematic narrative reviews, prepared...

The purpose of this prospective randomized controlled clinical trial was to evaluate the effect oral administration bromelain on discomfort after mandibular third molar surgery.Eighty-four consecutive patients requiring surgical removal a single impacted under local anesthesia were randomly assigned receiving no drug (control group, Group A), postoperative 40 mg every 6 hours for days (Group B), preoperative 4 dexamethasone sodium phosphate as submucosal injection C), and plus D)....

Abstract Background One of the most recent innovations in bone augmentation surgery is represented by computer-aided-design/computer-aided-manufacturing (CAD/CAM) customized titanium meshes, which can be used to restore vertical defects before implant-prosthetic rehabilitations. The aim this study was evaluate effectiveness/reliability technique a consecutive series cases. Methods Ten patients need implant therapy were treated using CAD/CAM meshes. A digital workflow adopted design virtual...

Purpose: This pilot study evaluated and compared histomorphometric immunohistochemical characteristics of peri-implant bone tissue after implant site preparation using piezoelectric tips versus conventional drills. Material Methods: Six patients with bilateral partial edentulism underwent a splitmouth protocol. Twelve alveolar ridges were randomized into six control sites prepared drills (Drill Group); test inserts (Piezo Group). At 28 days surgery (T1), single-stage “study fixtures” 0.5 mm...

ABSTRACT Aims This non‐inferiority randomised clinical trial aimed to compare vertical bone gain (VBG), volumetric changes and incidence of complications after ridge augmentation (VRA) using perforated titanium‐reinforced dense‐polytetrafluoroethylene (PTFE) mesh covered by a collagen membrane (CM) or used alone. Materials Methods Thirty patients with defects were randomly assigned receive VRA either PTFE + CM Meshes removed 9 months. Clinical assessments included complication rates,...

Background: The single‐flap approach (SFA) consists of the elevation a limited mucoperiosteal flap to allow surgical access periodontal defects from either buccal or oral aspect only, leaving interproximal supracrestal gingival tissues intact. aim present randomized controlled trial is assess effectiveness SFA used for debridement deep intraosseous compared double‐flap (DFA). Methods: Fourteen patients were treated according principles and 14 received DFA. In all patients, root surfaces...

This randomized clinical trial aimed to investigate the relationships between insertion torque, implant stability quotient (ISQ), and crestal bone loss (CBL) of implants placed in fresh or 12-week healed extraction sites.Forty patients were randomly assigned one two groups had immediately (test group, n = 20) 12 weeks after (control at premolar molar sites. For all implants, torque ISQ scores loading recorded. Patients followed for up months.Implant success was 100% both groups. No...

Abstract Objectives To determine whether and to what extent the additional application of plasma rich in growth factors ( PRGF ) an extraction socket may influence early bone deposition, as assessed by micro‐computed tomography (micro‐ CT scan well histomorphometric markers. Material methods Twenty‐eight patients (age range: 34–74 years) contributing 36 sockets were included study. Sockets either treated with group; 18 sites 11 patients) or left spontaneous healing (control 17 patients)....

ABSTRACT Purpose: Many authors have emphasized that immediate loading protocols enable better esthetic results to be achieved compared with delayed loading, especially in the case of postextraction implants are capable maintaining original esthetics soft tissues. The aim this study was establish correlations between interproximal crest, papilla, and marginal facial gingiva immediately loaded by evaluating clinical radiographic data. Materials Methods: Fifty‐eight consecutive patients...
