Clinical Trial 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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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	probing depth	peri-implant probing depth detected by periodontal probe examined by a peridontal probe at six sites around the crown	baseline to 1-year
Secondary	bleeding on probing	percentage of sites with bleeding on probing examined by a peridontal probe at six sites around the crown	baseline to 1-year
Secondary	Pink Esthetic Score (0-14)	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.	baseline to 1-year
Secondary	thickness of buccal bone plate	the distance between the implant's facial contour and the outside surface of the buccal bone measured by cone beam computor tomograph.	baseline to 1-year
