This investigation examined the clinical and radiographic outcomes of a newly designed triangular-neck implant in patients with partial tooth loss. Sixteen participants, averaging 58.3 years of age, received a total of 25 implants placed in healed sites of both the maxilla and mandible, with diameters of 3.3 mm and 3.9 mm. Evaluations were performed at the time of prosthetic placement, serving as baseline, and repeated after an average follow-up of 15.6 months. The main focus was on interproximal peri-implant bone changes, with mesial and distal measurements averaged for analysis, while secondary assessments included peri-implant probing depth (PPD) and bleeding on probing (BoP). Statistical comparison using paired t-tests showed no significant differences in bone levels from baseline (mesial: 0.45 ± 0.47 mm, distal: 0.57 ± 0.69 mm) to follow-up (mesial: 0.59 ± 0.42 mm, distal: 0.78 ± 0.59 mm). Likewise, PPD and BoP values remained stable over time. These findings suggest that the triangular-neck bone-level implant can be effectively used in partially edentulous patients, though larger and controlled studies are needed to corroborate these preliminary clinical and radiographic observations.
