The present in vitro study aims at comparing the ablation volume obtained with commercially available RITA’s StarBurst® XL (dry type) and StarBurst® Xli-e (wet type) multi-tine electrodes during radiofrequency ablation (RFA) procedure. The experiments have been conducted on polyacrylamide based tissue-mimicking phantom gel whose thermo-electric properties are similar to that of the soft tissues. A temperature-controlled RFA has been performed utilizing AngioDynamics RITA 1500X® radiofrequency generator. The maximal longitudinal and maximal transverse dimensions of the coagulated phantom gels have been measured from which the derived ablation volume has been calculated. Further, the temperature distribution and power delivered with the dry type and wet type electrodes have been compared. The in vitro study revealed that the efficacy of wet type electrode is more pronounced as compared to the dry type electrode. Moreover, it has been found that both the electrodes are capable enough of producing ablation volume up to 5 cm in diameter.

BACKGROUND Peri-implantitis is an inflammatory reaction surrounding the hard and soft tissues of the implant that is functional in the patient's mouth. If left untreated, this might lead to further bone loss, loosening of the implant and the ultimate failure of the implant. There are many treatment modalities that have been suggested to treat periimplantitis, but there are no set guidelines or protocols for the same. Implantoplasty seems to be a viable option for treating peri-implantitis, as it involves the smoothening of the macro geometry of the supracrestal exposed implant surface thus reducing the plaque accumulation and ultimately preventing the bacterial recolonization and preventing the implant from failure. This study was done to evaluate the smoothness and the fracture resistance of the implants treated by implantoplasty and as an effective treatment for peri-implantitis. METHODS This in-vitro study was done on 5 failed implants, in which 4 were subjected to a sequence of dental burs and prophy paste and 1 implant was kept as a control. They were subjected to laser topography analysis to determine the smoothness after implantoplasty, and their fracture resistance was also checked in Instron. RESULTS Implant no. 4 subjected to both dental burs and prophy paste was considered to be the smoothest with the laser topography of 2.049 mm compared to the control that was 3.132 mm. Also, the fracture resistance between the implants and the control was similar. CONCLUSIONS In conclusion implantoplasty is a suggested treatment option for patients with periimplantitis keeping in mind the practical difficulties of the procedure.

The Relationship

Aim: To compare and evaluate the implant stability quotient (ISQ) measurements by two different radio frequency analysis (RFA) machines, Osstell Mentor and PenguinRFA. Materials and Methods: Twenty bone-level implants (3.7 × 10 mm2) were placed on a bovine bone in this in vitro study. The ISQ measurements were performed with the PenguinRFA and Osstell Mentor machines using the multipeg of the Penguin system. The measurements were repeated three times for each direction and an average ISQ value was calculated. The results were averaged (mean ± SD) and the intraclass correlation coefficient (ICC) was calculated to assess the relationship between the measurements. Result: The mean ISQ values for the Osstell and Penguin machines were 77.60 + 2.11 and 78.05 + 2.04, respectively. The ICC was 0.958. The ISQ values obtained from the Osstell and Penguin machines were significantly compatible ( P < .05). Conclusion: Both of the RFA devices provided similar and reliable ISQ measurements.
