Immediate Implant Placement With or Without Buccal Bone Dehiscence

Completed

• Conditions: Dental Implant Failed
• Interventions: Procedure: gap filling; Procedure: flap elevation and guided bone regeneration; Procedure: connective tissue graft

• Registration Number: NCT05445986
• Lead Sponsor: Shanghai Ninth People's Hospital Affiliated to Shanghai Jiao Tong University

Brief Summary

Immediate implant placement has been advantageous in terms of reduced treatment time and fewer surgical interventions. Given the fact that the level of buccal bone acts as a major prognostic factor for IIP, the indications for immediate implant placement were suggested to be limited to intact alveolar sockets.In recent years, many attempts have been performed to compensate for the alveolar ridge resorption in immediate implant placement in compromised sockets. The clinical outcomes of IIP with guided tissue regeneration and connective tissue grafting using papilla preservation technique in compromised extraction sockets has not been previously reported.

Arm && Interventions

Group	Intervention	Description
group1	gap filling	socket with intact buccal bone plate
group 2	flap elevation and guided bone regeneration	socket with damaged buccal bone plate
group 2	connective tissue graft	socket with damaged buccal bone plate
group1	connective tissue graft	socket with intact buccal bone plate
group 2	gap filling	socket with damaged buccal bone plate

Primary Outcome Measures

Name	Time	Method
mucosa recession	baseline to 1-year	The height of the crown was measured by a peridontal probe in mid-facial aspect. The difference of the height of the crown over time was calculated as mucosa recession

Secondary Outcome Measures

Name	Time	Method
probing depth	baseline to 1-year	peri-implant probing depth detected by periodontal probe examined by a peridontal probe at six sites around the crown
bleeding on probing	baseline to 1-year	percentage of sites with bleeding on probing examined by a peridontal probe at six sites around the crown
Pink Esthetic Score (0-14)	baseline to 1-year	Seven parameters were assessed:mesial papilla, distal papilla, soft tissue level, soft tissue contour, alveolar process deficiency, soft tissue color, and soft tissue texture. Each parameter was scored as 2,1,0.
thickness of buccal bone plate	baseline to 1-year	the distance between the implant's facial contour and the outside surface of the buccal bone measured by cone beam computor tomograph.
