Immediate Implant Placement With or Without Buccal Bone Dehiscence

NCT05445986 | Completed

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.

Conditions

Dental Implant Failed

Outcome Measures

Primary Outcomes (1)

• mucosa recession

  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

  baseline to 1-year

Secondary Outcomes (4)

• probing depth

  baseline to 1-year

• bleeding on probing

  baseline to 1-year

• Pink Esthetic Score (0-14)

  baseline to 1-year

• thickness of buccal bone plate

  baseline to 1-year

Study Arms (2)

group1

socket with intact buccal bone plate

Procedure: gap filling; Procedure: connective tissue graft

group 2

socket with damaged buccal bone plate

Procedure: flap elevation and guided bone regeneration; Procedure: gap filling; Procedure: connective tissue graft

Interventions

flap elevation and guided bone regeneration PROCEDURE

to rebuild the alveolar ridge convexity

group 2

gap filling PROCEDURE

to use biomaterials to fill the jumping gap

group 2; group1

connective tissue graft PROCEDURE

to change the soft tissue phenotype by connective tissue graft

group 2; group1
