Methodology

The patient was diagnosed using thorough pre-operative analysis, which included a history, clinical [Table/Fig-4], radiographic examination, and standard blood tests. Each patient's intra-arch connection was assessed using diagnostic castings. Standardized intraoral periapical radiographs employing the long cone paralleling method, as well as panoramic radiographs [Table/Fig-5a], were used to analyze bone and surrounding tissues. A diagnostic stent was made with a 5 mm diameter steel ball at the planned implant position, and a second panaromic radiograph [Table/Fig-5b] was obtained. The standardized diameter of the steel ball served as a reference for calculating the radiography distortion factor. The acquired picture allowed for an accurate evaluation of the available bone height above the mandibular canal while selecting implant length. Ridge mapping was performed using a bone caliper to assess the breadth of the alveolar ridge before selecting an implant diameter. Each patient received a custom-made acrylic resin surgical stent to provide the best possible location for implant implantation. Oral hygiene recommendations are given following oral prophylaxis to create a more favorable mouth environment for wound healing.

Before surgery, the patients washed their mouths with 0.12% chlorhexidine mouthwash. Crestal incision was performed under local anesthetic infiltration (2% lignocaine with 1:80,000 adrenaline), followed by reflection of the whole mucoperiosteal flap. The point of entrance was indicated deep in the bone via the guiding hole in the surgical stent with a spherical bur. The implant bed preparation began with a conventional pilot drill at the specified spot, with abundant cold saline irrigation both inside and externally. The angulation of the osteotomy drill was verified using a paralleling tool. Sequential drilling was carried out utilizing ordinary drills and a physiodispenser. The longest and broadest pre-selected implants were threaded into the prepared site up to the crestal level using a ratchet and insertion tool. All implants demonstrated satisfactory primary stability. After implant insertion and proper stability, the implant mount was removed using a hex wrench, and the cover screw was installed. All implants utilized had internal hex; the occlusal (platform) portion of the implant receives the prosthetic component of the restoration. This implant was put at the crestal bone level. The implant diameter varied from 3.3 to 4.2 mm, with a length of 10 to 13 mm. To safeguard the implant locations, soft tissue margins were sutured after they had been placed.
