Soft tissue thickness AND implant AND bone

BACKGROUND: The significance on the association between the peri-implant bucco-lingual dimension (BLD) at the stage of implant placement and the occurrence of biological and esthetic complications is yet unknown. MATERIAL AND METHODS: Systematic screening of electronic sources was carried out to identify clinical and preclinical studies reporting on the baseline BLD and/or buccal bone thickness (BBT) values. A secondary objective was to assess the effect of simultaneous grafting at sites with deficient or no buccal bone wall (BBW) at baseline...

OBJECTIVES: The aims of Working Group 1 were to address the role (i) of the buccolingual bone dimensions after implant placement in healed alveolar ridge sites on the occurrence of biologic and aesthetic complications, and (ii) of soft tissue augmentation (STA) on the stability of clinical, radiographic, and patient-related outcomes of implant treatments. MATERIALS AND METHODS: Two systematic reviews were prepared in advance of the Consensus Conference and were discussed among the participants of Group 1...

BACKGROUND: Platelet-rich fibrin (PRF) is commonly used for ridge preservation following tooth extraction. However, its effectiveness diminishes over a period of two weeks as it is resorbed and loses its biological activities. Therefore, this clinical study aims to evaluate the effect of recurrent application of concentrated PRF (C-PRF) inside the extraction socket on the hard and soft tissue alterations. METHODS: Twenty patients requiring single tooth extraction and replacement with a dental implant were randomized into one of two ridge preservation approaches: Advanced PRF plus alone (Control group) or advanced PRF plus with the recurrent application of a C-PRF inside the socket every two weeks for 2 months (four times)...

BACKGROUND AND OBJECTIVE: In recent years, the concept of the peri-implant phenotype has become a new standard for the clinical evaluation of the soft and hard tissues surrounding dental implants. Improving this phenotype enhances the likelihood of achieving long-term favorable results and is a necessary consideration during implant planning. Stable peri-implant tissue support is also crucial for the functional and aesthetic value of implant restoration. Herein, the authors review the clinical significance of the peri-implant phenotype and assess the timing of treatment strategies for improving peri-implant phenotype elements...

OBJECTIVES: To evaluate the ridge alterations and esthetic outcome 1 year after immediate implant placement using the dual-zone (DZ) technique versus the bone shielding concept in patients with intact thin-walled sockets in the esthetic zone. MATERIAL AND METHODS: This randomized clinical trial included 26 patients with nonrestorable maxillary teeth in the esthetic zone who were randomly assigned to two groups (n = 13 each) to receive immediate implants using either the bone shielding concept or DZ...

Purpose: To evaluate the efficacy of split-thickness labial eversion periosteoplasty (EPP) for soft tissue closure in horizontal ridge augmentation of posterior mandibular regions using a bone shell onlay grafting technique. Materials and Methods: Sixteen patients (12 female and 4 male; mean age: 46.2 ± 8.7 years) with 18 horizontal bone defects in posterior mandibular regions were included for lateral onlay bone grafting using the bone shell technique. After lateral bone augmentation, the EPP was used for soft tissue closure and was prospectively followed up for wound healing efficacy using a modified scoring index...

BACKGROUND: This study compared the effectiveness of three bone grafting materials used for treating class II fresh extraction sockets in the esthetic zone with immediate implant placement using Vestibular Socket Therapy (VST) to evaluate the pink esthetic score (PES), peri-implant mucosal levels (PML), and facial bone thickness (FBT). METHODS: Twenty-four surgical sites in the maxillary anterior region presented with type II socket defects received immediate implants and simultaneous bone grafting with either a collagen plug soaked in blood, demineralized bone matrix Grafton, or a particulate mixture of 2/3 autogenous bone chips and 1/3 deproteinized bovine bone mineral MinerOss X...

OBJECTIVE: The objective of this study is to compare the clinical efficacy of angulated screw channel abutment applied in the anterior area with regular cemented crowns. MATERIALS AND METHODS: Forty-eight patients were included and divided into two groups: the angulated screw channel group (ASC) and regular cemented group (RC) in this retrospective cohort study. The evaluation criteria included implant/restoration survival rate, keratinized mucosa width (KMW), bleeding on probing rate (BOP%), probing depth (PD), pink aesthetic score (PES), mechanical/biological complications, emergence angle (EA), the site of implant axis penetrate (SA), marginal bone loss (MBL), and buccal bone thickness (BBT) at 0 mm, 1 mm, 3 mm, 5 mm below the implant shoulder were evaluated in immediate postoperative (T0) and follow-up period (T1)...

BACKGROUND: Many techniques have been proposed to address post-extraction ridge resorption, which often represents a concern, especially in the esthetic region. PURPOSE: The purpose of the present, prospective, multicenter, single cohort study was to investigate, up to 1 year of function, the effectiveness of a protocol for alveolar ridge preservation involving implants with laser-microgrooved surface immediately placed in fresh extraction sockets. MATERIALS AND METHODS: Twenty eight patients candidate to tooth extraction in the esthetic zone (site 15-25 and 35-45) were treated by immediate placement of a single laser-microgrooved implants with the adjunct of a highly porous anorganic porcine bone mineral matrix and a collagen wound dressing...

MATERIALS AND METHODS: Included in this retrospective study were patient records of 3583 implant placements utilized from an online dental information archiving software (DIAS). Clinical and radiographic assessments were conducted concurrently with implant placement (baseline) and 1 year post surgery...

Since class II malocclusion and lack of space within the dental arch due to early loss of deciduous molars is a common orthodontic problem in the Polish population, bone-anchored distalizers are becoming more and more popular. The aim of the present study was to evaluate palatal soft and hard tissue thickness using cone beam computed tomography (CBCT) at the area of micro-implant placement of two appliances for maxillary first molar distalization: Beneslider and TopJet distalizer. The study data were 100 consecutively selected CBCT images (53 of men and 47 of women)...

AIM: To compare subepithelial connective tissue grafts (SCTG) versus guided bone regeneration (GBR) for the treatment of small peri-implant dehiscence defects in terms of profilometric (primary outcome), clinical, and patient-reported outcome measures (PROMs). METHODS: Sixteen patients who presented with small buccal bone dehiscences (≤3 mm) following single implant placement were recruited. Following implant placement, buccal bone defect sites were randomly treated either with a SCTG or GBR...

The surgical repair of articular cartilage remains an ongoing challenge in orthopedics. Tissue engineering is a promising approach to treat cartilage defects; however, scaffolds must (i) possess the requisite material properties to support neocartilage formation, (ii) exhibit sufficient mechanical integrity for handling during implantation, and (iii) be reliably fixed within cartilage defects during surgery. In this study, we demonstrate the reinforcement of soft norbornene-modified hyaluronic acid (NorHA) hydrogels via the melt electrowriting (MEW) of polycaprolactone to fabricate composite scaffolds that support encapsulated porcine mesenchymal stromal cell (pMSC, three donors) chondrogenesis and cartilage formation and exhibit mechanical properties suitable for handling during implantation...

OBJECTIVES: Postoperative oral health-related quality of life is procedure-dependent and may vary during early healing. There is scarce evidence on patient-reported outcome measures (PROMs) after extraction and guided bone regeneration (GBR) or on the clinical parameters influencing PROMs. This prospective observational study aimed to evaluate PROMs during the first 2 weeks following extraction and GBR and correlate them with clinical parameters. METHODS: Patients undergoing extraction and GBR (bone graft and resorbable membrane) at a single tooth-bound site were recruited...

Oxygen is one of the essential requirements for cell survival, retention, and proliferation. The field of regenerative medicine and tissue engineering (TE) has realized considerable achievements for the regeneration of tissues. However, tissue regeneration still lacks the full functionality of solid organ implantations; limited cell survival and retention due to oxidative stress and hypoxia in the deeper parts of tissues remains a perpetual challenge. Especially prior to neovascularization, hypoxia is a major limiting factor, since oxygen delivery becomes crucial for cell survival throughout the tissue-engineered construct...

While the addition of a connective tissue graft (CTG) has been found to increase gingival thickness and reduce facial gingival recession in immediate implant placement and provisionalization, it is associated with significant loss of buccal bone thickness. Loss of buccal bone thickness is thought to be related to preparation of the facial CTG recipient site. This technical report presents a modification of the dual-zone therapeutic concept where the bone zone is grafted with bone graft, and the tissue zone is grafted with tuberosity CTG without elevation a facial partial or full-thickness envelope...
