Background: The preservation of bone volume immediately after tooth removal might be necessary to optimize the success implant placement in terms esthetics and function. objectives this randomized clinical trial were two‐fold: 1) compare dimensional changes following extraction with plus ridge using corticocancellous porcine a collagen membrane; 2) analyze histologic histomorphometric aspects extraction‐alone sites grafted sites. Methods: Forty subjects who required enrolled study. Using...

Background: Implants placed immediately after tooth extraction offer several advantages, but many authors have reported problems in filling the residual gap between implant and socket walls. Barrier grafting techniques been tested yield varying results, so it has suggested that timing of placement may be important for success. The aim this study was to analyze bone healing coronal remodeling around 35 implants, 20 removal 15 6 8 weeks extraction. Methods: All implants were submerged within...

Abstract Introduction As a consequence of extraction, the height buccal wall tends to decrease and results in disappearance bundle bone. To modify bone remodelling after various ridge preservation techniques have been proposed. The present research was drawn up with following considerations mind: evaluate compare changes hard soft tissues post‐extraction sockets which received procedure, had healed naturally. Materials methods Each patient randomly allocated test or control group using...

Abstract Objectives: The aim of the present study was to investigate in a randomized‐controlled clinical trial performance rotary instruments compared with piezoelectric device during maxillary sinus floor elevation. Materials and methods: Thirteen patients who required bilateral augmentation for implant–prosthetic rehabilitation were included this study. A within‐patient control carried out. osteotomy access performed on one side maxilla using piezosurgery (test sites) other conventional...

To evaluate the bacterial microflora present inside implant connection and in peri-implant sulcus fluid of healthy implants, to analyze relationships between these harboring sites for four different systems after at least 5 years functional loading.A cross-sectional study was performed involving 40 patients treated with metal-ceramic cemented bridges supported by two implants functionally loaded years. Four implant-abutment connections were studied: external hexagon (control group), double...

Abstract Objective The aim of this study was to analyze clinical and microbiological characters in subjects implants affected not by peri‐implantitis. Additionally, same features were analyzed also intra‐individually, comparing healthy diseased within the subject. Materials methods A total 534 patients who received at least 1 implant coming routine check‐up or spontaneous visits University Valencia recruited. Clinical parameters including Bleeding on probing (BoP), Probing pocket depth ( PPD...

To investigate whether specific predictive profiles for patient-based risk assessment/diagnostics can be applied in different subtypes of peri-implantitis.This study included patients with at least two implants (one or more presenting signs peri-implantitis). Anamnestic, clinical, and implant-related parameters were collected scored into a single database. Dental implant was chosen as the unit analysis, complete screening protocol established. The affected by peri-implantitis then clustered...

Background: Implants placed immediately after tooth extraction have shown high percentages of clinical success. Few studies in the scientific literature observed horizontal bone remodeling buccallingual direction immediate placement implants. The aim this study was to analyze healing and coronal around 15 implants removal without use guided regeneration (GBR) techniques. Methods: Ten patients received a total single‐rooted teeth. All were within alveolar confines, limiting, most cases, small...

Some of the original surgical protocols for implant surgery have been reassessed to satisfy patient's continuously increasing expectation shorter rehabilitation time, improved esthetics, and increased comfort. The aim this study was evaluate 12-month clinical success 18 single-tooth implants inserted immediately after tooth extraction restored same day with non-functional loading.A total patients (12 women six men), 22 60 years old, were enrolled in study. Eighteen single fresh sockets...

Background: The alveolar ridge undergoes reabsorption and atrophy subsequent to tooth removal thus exhibits a wide range of dimensional changes. Preservation the crest after extraction is essential enhance surgical site before implant fixture placement. aim this randomized clinical study investigate compare need for additional augmentation procedures at insertion, as well success rate marginal bone loss implants placed in grafted sites versus those naturally healed sites. Methods: Forty...

Background: The preservation of hard and soft tissue volume, partially lost after tooth removal, can potentially reduce the need for more demanding augmentation procedures used in implant‐supported rehabilitation. objective this research study is to investigate effect filling with xenogeneic material postextractive sockets two surgical (flapless versus flapped). Methods: In prospective randomized clinical survey, types socket were performed on groups patients: control, treated via...

Tooth extraction is followed by marked osseous changes of the residual alveolar ridge including severe bone alterations both in height and width. However, such remodelling could jeopardize subsequent implant insertion for two main reasons. Firstly, absence adequate levels makes placement impossible; secondly, aesthetic problems fabrication implanto-supported restoration be caused serious re-absorption. Thus, it crucial importance that dental surgeon knows how crest when a single tooth has...

Abstract Background The insertion torque value has been extensively used as an indicator for implant primary stability, which is considered a determining parameter the implants success. Purpose goal of present randomized clinical trial was to evaluate and compare outcome placed with high (between 50 Ncm 100 Ncm) regular (within in healed ridges. Materials Methods Partially edentulous patients, missing one or more mandibular maxillary teeth, having adequate amount bone, requiring placement,...

The present double-blind randomized clinical trial aimed to compare the efficacy in reducing dentin hypersensitivity of a dentifrice formulation containing nano-hydroxyapatite with fluoride and placebo.105 subjects were recruited participate study. A computer-generated random table blocking one three study treatments was used order have 35 per group: 1) 15% toothpaste, fluoride-free; 2) toothpaste; 3) placebo. Groups 1, 2, 3 instructed brush their teeth for 2 minutes twice day provided...

To compare implants in healthy conditions and with peri-implantitis regard to their clinical parameters the microbiologic composition at peri-implant sulcus, inside implant connection, gingival sulcus of neighboring teeth.A cross-sectional study was performed including consecutive patients peri-implantitis. Clinical for which were screened included bleeding on probing, pocket depth, plaque index six sites. Samples analysis obtained from three locations: teeth. Quantitative real-time...

Abstract Objective The aim of this study was to evaluate and compare the histological histomorphometric features two different procedures carried out in extraction socket grafting; namely, flapped flapless technique. Materials methods Patients considered eligible for were randomized receive tooth ridge preservation with porcine bone collagen membrane, a full thickness mucoperiosteal flap primary soft tissue closure (control group), or, procedure secondary (test group). After 3 months...
