Filter by:Objective of the present study was to assess the peri-implant soft tissue profiles between argon plasma pre-treated (PT) and non-treated (NPT) abutments by comparing clinical and histological parameters 2 months after abutment placement.
Our long-term goal is to generate evidence for the creation of successful implant restorations and ideal supporting tissues in adequate health by utilizing patient-tailored implant protocols such as the use of customized computer-aided design and computer-aided manufacturing (CAD/CAM) healing abutments. With this study, the investigators intend to recruit patients requiring a single implant placement and implant crown in molar areas. Patients will be randomly assigned to either the control group that will receive standard healing abutments or the test control group that will receive customized CAD/CAM healing abutments. Patients will be followed for six months after the delivery of the implant crowns. The central hypothesis is that the use of customized CAD/CAM healing abutments will demonstrate improved outcomes in terms of hard and soft tissue volume stability and clinical parameters as compared to the use of standard healing abutments. Aim 1 will measure soft and hard tissue changes around dental implants when customized CAD/CAM healing abutments are utilized as compared to standard healing abutments. Soft tissue stability will be measured utilizing intraoral digital scans, while osseous levels will be measured utilizing CBCT scans. Soft and hard tissue volumetric and linear changes will be measured by digital scan superimposition at the time of crown delivery and 6 months thereafter. Volumetric and linear changes will be compared within each group at different time points and between the test and control group to determine if the use of customized CAD/CAM healing abutments is advantageous in terms of maintaining peri-implant soft and hard tissue stability. Aim 2 will assess different clinical measurements around dental implants to analyze if the use of customized CAD/CAM healing abutments will demonstrate improved plaque control and peri-implant health as compared to standard healing abutments. Plaque index (PI), gingival index (GI), probing depths (PD), and bleeding on probing (BOP) will be obtained at the time of crown delivery and at 3 and 6 months. Clinical measurements will be compared between the test and control group to determine if the use of customized CAD/CAM healing abutments will aid in obtaining a natural looking restoration that would result in improved clinical parameters that measure peri-implant health. Aim 3 will compare the degree of patient satisfaction using a visual analogue scale (VAS) in patients that received an implant restoration following the use of a customized CAD/CAM healing abutment as compared to standard healing abutments. Patients will complete a VAS questionnaire that will evaluate patient perception of pain, esthetics, ability to chew, and ability to clean. Scores will be compared among groups to evaluate if there is a difference in patient-centered outcomes when customized healing abutments are used as compared to standard healing abutments.
Aim of the present investigation will be to evaluate the efficacy and safety of a granulate of rhBMP-2- loaded bovine bone mineral (rhBMP-2-BBM) as alveolar bone regeneration procedure following tooth extraction. Forty (40) patients (both sex; age 18 years and older) requiring extraction of one (1) hopeless tooth (incisor, canine or premolar with loss of bone height of 5 mm or more in buccal alveolar wall), followed by alveolar bone regeneration (ABR) and placement of an endosteal implant will be enrolled into the study. After exodontia, participants will be randomized and divided into two groups: in Experimental Group the socket will be grafted with rhBMP-2-BBM granules (1.0-0.25 mm); in Control Group the sockets will be grafted with Bio-Oss granules (1.0-0.25 mm) and covered with porcine collagen barrier membrane (Bio-Gide). The end of the study will be fixed at the implantation surgery, seventeen (17) weeks after exodontia an ABR. Cone beam computed tomography (CBCT) scans will be made, immediately after (0), and sixteen (16) weeks after exodontia an ABR and the gain in alveolar bone height will be estimated and used as the primary outcome for comparison of both groups. As secondary efficacy outcomes the change in alveolar bone width estimated from the CBCT scans; initial (0) and at seventeenth (17th) week after tooth extraction; the change in dental arch dimensions estimated from tridimensional models obtained from intraoral scans at one week before (-1) and sixteen (16) weeks exodontia an ABR; and the amounts of new bone, remnant material and connective tissue histomorphometrically measured in a bone biopsy collected during the implantation surgery at seventeenth (17th) week, will be considered. Healing of gingival tissues at first (1st) and second (2nd) week and incidence of adverse reactions at first (1st), second (2nd) and sixteenth (16th) week, are used as secondary safety outcomes.
Isolated sinus pneumatization after single tooth extraction indicate sinus lifting for proper implant placement. The conventional way of using osteotomes to elevate the sinus is annoying to patient and also does not give the needed amount of bone around the implant. Introducing new intervention of Densah Burs helps increase bone gain around implant and decrease the patient discomfort.
Hybrid Funnel Technique arises from the union of subtractive and non-subtractive techniques for implant site preparation. Hybrid funnel technique is performed with specially designed drills and osteotome. the aim of the study is to examine marginal bone level and implant stability of implants inserted with two different techniques for the surgical implant site preparation.
In this study, the dimensional changes of the labial alveolar ridge are digitally assessed after immediate implant placement using the socket shield technique with computer guided sectioning of the root.
A prospective observational study guided by the guidelines of Strengthening The Reporting Of Observational Study in Epidemiology (STROBE) in 2014, that will be conducted to evaluate implant stability using three devices; Osstell®, Peiotest® and AnyCheck® and comparing the results.
To investigate clinical outcomes of transcrestal maxillary sinus floor elevation performed with an injectable xenograft in gel form, analyzing variables possibly influencing the results. Patients needing unilateral sinus floor elevation (residual crestal height <5 mm) for the placement of a single implant were enrolled. Xenograft in gel form was injected through a crestal antrostomy in order to elevate sinus membrane and fill the sub-antral space. Simultaneous implant placement was performed when adequate primary stability was achievable. Graft height was measured immediately after surgery (T0) and after six months of healing (T1). Univariate and multivariate regression models were built to assess associations between clinical variables with implant survival and graft height at T1.
The Narrow GM Implants were designed for oral functional rehabilitation using dental implants, allowing for treatment of patients with different bone qualities in the region of lateral incisors in the maxilla or the region of lateral and central incisors in the mandible. The objective of the study is to confirm the long-term safety and clinical performance of implants and abutments of the Narrow GM System in a daily dental practice setting, by means of a prospective collection of clinical data in an observational study using these devices. Devices will be used according to standard routine in daily practice, according to all indications as specified by the manufacturer in the instructions for use (IFU). 55 patients (needed to obtain a sample size of 55 implants) will be followed for 36 months and monitored for Adverse Events by the Investigators until the last protocol-related procedure of a patient is completed.
