Triple-Abutment System with Hyperbolic Paraboloid Geometry: Prosthetic loading will be performed on osseointegrated morse taper dental implants using a fixed implant-supported rehabilitation with a triple-abutment system featuring hyperbolic paraboloid geometry. Metal-ceramic prostheses will be cemented over the abutment components. All procedures will be performed by a single operator.
This prospective clinical study aims to evaluate the clinical and radiographic outcomes of a novel triple-abutment system with hyperbolic paraboloid geometry installed on Morse taper dental implants. The system is designed to support three adjacent crowns on a single implant, aiming to optimize load distribution and preserve peri-implant tissue stability.
Thirty systemically healthy adults missing three adjacent teeth will undergo implant placement, followed by a healing period of approximately three months for osseointegration prior to prosthetic loading. Metal-ceramic restorations will then be cemented over triple abutments. Clinical and radiographic evaluations will be performed at T1 (3-4 months after prosthetic loading) and T2 (12-18 months after prosthetic loading).
The primary outcome will be marginal bone level change assessed by standardized periapical radiographs. Secondary outcomes include probing depth, bleeding on probing, plaque index, keratinized mucosa height, and patient-reported satisfaction. The study aims to investigate whether this innovative abutment design provides stable peri-implant conditions and favorable clinical performance when applied to Morse taper implants.
