Esthetic Outcomes of Single Immediate Implant Placement
Esthetic Outcomes of Single Immediate Implant Placement With Immediate Restoration Performed With Two Surgical Techniques
Study Overview
Status
Conditions
Detailed 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. 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.

Time Frame |
---|---|
Change in Gingival Margin Location on the Buccal, Mesial and Distal Compared With Pre-operative Baseline and Post-operative Baseline
Time Frame: Change from Pre-operative Baseline in Gingival Margin Location at 3, 6 and 12 months and change from post-operative baseline at 3 and 6 months

Measure Description |
Time Frame |
---|---|---|
Change in Buccal Horizontal Ridge Dimensions
Time Frame: Change from Baseline in Buccal Horizontal Ridge Dimensions at 3, 6 and 12 months
|
Horizontal changes of the buccal ridge was calculated through the use of acrylic stents and digital overlays (3Shape D800, Biomet 3i, Palm Beach Gardens, FLS).
The acrylic stents were obtained from the pre-surgical plaster casts and they were repositioned on the plaster casts obtained at 3, 6 and 12 months.
Discrepancies between the acrylic stent and the plaster cast were measured with a probe.
The digital cast overlays were used to analyze changes from pre-surgical to 3 and from 3 to 6 months).
The plaster casts were scanned and changes were analyzed with the use of a software.
