Dental Implant Failed
Conditions
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.
Interventions
PROCEDUREflap elevation and guided bone regeneration
to rebuild the alveolar ridge convexity
PROCEDUREgap filling
to use biomaterials to fill the jumping gap
PROCEDUREconnective tissue graft
to change the soft tissue phenotype by connective tissue graft

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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
| Measure | Time frame | Description |
|---|---|---|
| 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. |
