In this study a tooth that needs to be extracted will be replaced by an implant (artificial root) placed at the same appointment as the extraction. The investigators want to observe how the gums change shape with healing in two different scenarios: 1. If the soft tissue around your tooth is thin, following extraction and implant placement an extra soft tissue graft (taken from your palate) in the area in order to increase the thickness of your gums after healing. 2. If the soft tissue around your tooth is thick, the implant will be placed without a soft tissue graft. Previous studies have shown that both methods work and can give good results. In fact the two methods are used routinely but they have never been compared objectively to one another in the same research study. The main purpose of this study is to evaluate if there is any difference in terms of esthetic outcomes between these two treatment modalities after a crown has been placed on the implant.
The primary objective of this study is to demonstrate non-inferiority of the Straumann Bone Level Ø 3.3 mm NC SLActive Roxolid Implants compared to Straumann Bone Level Ø 4.1 mm RC SLActive Roxolid Implants based on mean crestal bone level changes measured between surgery and 12 months post-implant placement. The secondary objectives will assess differences in clinical outcomes between the test and control implants, including implant success and survival, gingival recession, subject satisfaction and additional early bone level measurements.
The purpose of this study is to determine which implant-abutment design is more likely to promote early soft-tissue healing processes and/or will enhance longitudinal peri-implant bone and soft-tissue health.
40 consecutive adult patients, requiring the insertion of dental implants in the aesthetic area (from second premolar to second premolar) will be enrolled in the study. At the time of surgery, a full thickness flap will be elevated, the implant bed will be prepared according to the manufacturer's instruction and the implants will be then seated into the bone. T0 corresponds to the time of implant insertion, T1 to the time of healing abutment's connection (T0=T1 for single stage implants), and T2 corresponds to 1-year follow-up from healing abutment's connection. Cone Beam Computed Tomography (CBCT) scans will be taken immediately after abutment connection (T1) and 1-year after (T2). The midsagittal cut of each implant will be identified, and measurements will be made at predetermined levels. Horizontal facial bone thickness (HFBT) and Vertical facial bone level (VFBL) will be measured. HFBT will be measured at 0, 3, 6 and 9 mm apical to the implant platform. VFBL wil be the perpendicular distance from the implant platform to the most coronal point of the facial bone. Changes between T1 and T2 will be calculated.
Aim of the present study will be to evaluate if the platform switching and the flat abutment can modify the peri-implant marginal bone remodelling. A clinical assessment of the soft tissues will also be provided. 80 consecutively inserted dental implants will be included in this study. Maxillary and mandibular implants will be considered, both in frontal and posterior area. After 6 to 12 weeks, the definitive prosthetic abutment will be screwed and the temporary crown cemented. After 2 more months, the definitive porcelain crown will be delivered. The final outcomes will be collected after 1 year from implant insertion. Data will refer to the following timing: T0= implant installation T1= temporary crown cementation T2= definitive crown cementation T3= 1 year follow-up The 80 implants will be randomly divided into 4 groups of 20 implants each, with different implant/abutment design. Group 1: Tapered T3 Standard Collar implants + GingiHue abutments Group 2: Tapered T3 Standard Collar implants + Tissuemax IL abutments Group 3: Tapered T3 Prevail implants + GingiHue abutments Group 4: Tapered T3 Prevail implants + Tissuemax IL abutments On x-rays, the mesial and distal Marginal Bone Level will be measured and compared among and between the groups at the 4 different timing. Pocket Depth and Bleeding on probing (mesial, buccal, distal and lingual) will be measured at T0, T1, T2 and T3. Data will be statistically analyzed.
The aim of the study is to describe the changes found in C1 dental implants through their early healing period. Patients requiring a standard installation of one or two implants in the maxilla, without any need for bone augmentation, will be frequently followed for 90 days. In every meeting the implants' ISQ values (values denoting the implant stability as being measured by a dedicated, commercially available, appliance called 'Osstell'). The implants' measured ISQ values will be used to describe the changes that may be found in the implants' stability through their healing period. At the end of the study the patients will be referred to their treating doctor for the completion of implants' restoration (i.e. crown).
The investigators are asking subjects to take part in a research study of soft tissue (gums) and bone (jawbone) healing around dental implants following tooth extraction. The investigators want to compare how the gums and the bone changes shape with healing in two different scenarios: 1. When the implant is placed at the same time the tooth is extracted. 2. When the tooth is extracted and then left to heal for a period of 4 to 8 weeks before the implant is placed. Previous studies have shown that both methods work and can give good results. In fact the two methods are used routinely as part of standard care but it is not known if the two procedures are equally good since they have never been compared in one same research study.
The study, with the ASTRA TECH Implant System, is comparing short implants (OsseoSpeed™) to standard length implants (OsseoSpeed™) in combination with bone grafting. The hypothesis is that the use of short implants in posterior maxilla with inadequate bone is as safe and predictable as placing standard length implants in combination with bone augmentation.
The purpose of this study is To demonstrate that there is no difference in change in bone level around P.004 implants between 1st stage surgery and 6 months post surgery when transmucosal implant placement is compared to submerged implant placement
