Resumen
Los implantes de una sola pieza de diámetro estrecho (NDI) muestran un excelente rendimiento clínico a los 5 años para los incisivos laterales maxilares ausentes. Esta solución fiable y estética ofrece altas tasas de supervivencia y mínimas complicaciones en pacientes con hueso limitado.
Área de la Ciencia:
- Dental Implantology; Prosthodontics; Periodontology
Sus antecedentes:
- Congenital maxillary lateral incisor agenesis is a common dental anomaly.; Limited alveolar bone presents a challenge for traditional implant rehabilitation.; Narrow-diameter implants (NDIs) offer a less invasive treatment alternative.
Objetivo del estudio:
- To evaluate the 5-year clinical performance of one-piece, smooth-necked NDIs.; To assess outcomes in patients with maxillary lateral incisor agenesis and limited alveolar bone.; To determine implant survival, success, and complication rates.
Principales métodos:
- Prospective multicenter study with 46 patients.; Flapless placement of Ø2.7mm smooth-necked NDIs with immediate loading.; Clinical and radiographic assessments at baseline, 1 month, 1 year, and 5 years.; Evaluation of marginal bone levels, soft tissue parameters, esthetics, and complications.
Principales resultados:
- 97.8% implant survival and 93.5% success rates at 5 years.; Mean marginal bone loss of 0.84mm at 5 years; stable soft tissue parameters.; High papilla preservation (89%) and favorable esthetic outcomes.; Minimal mechanical complications (2 cementation failures, 1 chipping).
Conclusiones:
- One-piece NDIs are a reliable and esthetic option for maxillary lateral incisor agenesis.; They provide a cost-effective, minimally invasive solution for patients with limited alveolar bone.; High survival rates and stable outcomes support their use in patient-centered care.
