Oval Abutment Versus a Circular Abutment in Dental Implants in the Anterior Maxillae

Objetive: The main objective of this clinical trial is to assess whether the oval section abutment of a 2.9mm implant achieves a greater covering of the tooth-implant papilla compared to a circular section abutment in 3.3mm implants in upper lateral incisors and lower central / lateral incisors.Material and methods: fourty patients received unitary implants of 3.3mm or 2.9 mm diameter to replace the absence of upper lateral incisor or lower central/lateral incisor with an edentulous space of at least 6.4mm (mesio-distally). Esthetic and clinical parameters were evaluated 12 months after installation of the prosthesis.Condition or disease: dental implantsIntervention/treatment: 3.3 or 2.9 mm diameter dental implantsPhase: Not Applicable

Inclusion Criteria:Patients >18 years of ageAbsence of upper lateral incisors or lower central / lateral incisors with an edentulous space of at least 6.4mm (mesio-distally).The teeth adjacent to the edentulous space must be natural.Patients who are in periodontal health.Signing of informed consent before entering the study.Exclusion Criteria:Patients with any systemic condition or disease that may interfere with oral surgery.History of radiotherapy.Patients smoking more than 20 cigarettes per day.Pregnant or breastfeeding patients.
