Esthetic Outcomes of Single Immediate Implant Placement
This trial is active, not recruiting.
|Conditions||gingival recession, bone loss, alveolar|
|Treatments||flapless immediate implant placement, flap assisted immediate implant placement, implant and temporary crown|
|Start date||December 2011|
|End date||September 2017|
|Trial size||39 participants|
|Trial identifier||NCT02435706, AAAI1840|
A randomized controlled trial of 12-month duration to compare gingival margin location, buccal horizontal ridge dimensions, and interproximal crestal bone levels following two surgical approaches for immediate placement of implants in the esthetic zone: one involving flap elevation and another using a flapless protocol.
|Intervention model||parallel assignment|
Change in Gingival Margin Location on the Buccal, Mesial and Distal
time frame: Change from Baseline in Gingival Margin Location at 3, at 6 and at 12 months
Change in Interproximal Crestal Bone Levels
time frame: Change from Baseline in Interproximal Crestal Bone Levels at 6 and 12 months
Change in Buccal Horizontal Ridge Dimensions
time frame: Change from Baseline in Buccal Horizontal Ridge Dimensions at 3, 3 to 6 months and 6 to 12 months
All participants at least 18 years old.
Inclusion Criteria: - Single non-restorable tooth in the anterior maxilla - Intact buccal plate or <5mm fenestration Exclusion Criteria: - Pregnancy - Current smokers >10 cigarettes/day - Parafunctional habits - Malocclusion or intent of orthodontic therapy in the future - Severe periodontal disease

|Description||In the test group, the implant will be placed according to standard protocol at a position engaging the palatal wall without elevation of a mucoperiosteal flap. In the control group, intrasulcular incisions will be carried out from one tooth distal to one tooth mesial to the extraction site and full thickness flaps will be elevated with periosteal elevator, including the papillae. The implant will be placed according to standard protocol at a position engaging the palatal wall, and the flaps will be sutured using a combination of interrupted and mattress sutures. In both groups, temporary restorations will be delivered immediately after implant placement provided that the implant shows primary stability and has engaged in the bone with an insertion torque of 25Ncm or more (Norton, 2004). In case of a lower insertion torque, the protocol will be abandoned, a cover screw will be placed, and a two stage implant protocol will be followed. All patients will be advised to receive a permanent restoration 6 months after surgery, if the implant is deemed to be successful (Misch et al., 2008).|
