Comparative evaluation of implant stability and esthetics by partial extraction therapy and immediate implant placement in maxillary anterior region: A clinical study
Venkateshwarapuram Rengaswami Balaji, Krishnaveni Boobalan, Manikandan DhanasekaranBackground:
Partial extraction technique is a method of immediate implant placement, wherein the segment of root is retained in the socket to establish a continuous blood supply and prevent resorption of buccal bundle bone. This study was designed to compare and evaluate implant stability and esthetics by partial extraction therapy (PET) and immediate implant placement in the maxillary anterior region.
Materials and Methods:
A total of 10 sites were included in the study and divided into two groups; the test group (PET) and the control group (immediate implant). The primary parameters assessed were implant stability, evaluated immediately, 3rd month and at 6th month; pink esthetic (PE) score, evaluated immediately, 3rd month and at 6th month; and cone-beam computed tomography for evaluating ridge width postoperatively and at the end of 6 months. The secondary parameters such as the Visual Analog Scale were assessed at the end of 24 h of surgical procedure; the sulcular bleeding index was evaluated at the 3rd month and 6th month; peri-implant probing depth was evaluated at the end of the 3rd month and 6th month.
Results:
At the end of the 6th month, the test group (PET) showed improvement in implant stability, PEs, and ridge width than the control group (immediate implant placement). However, the difference was not statistically significant.
Conclusion:
Implant placement by PET, serves as a dependable technique for preserving and maintaining alveolar bone and PEs as the retained root fragment within the socket prevents buccal bundle bone from resorption.
