Summary

This study aims to compare 2 different groups of patients with both a healed site in the upper posterior sector after extractions, one treated with ultra-short implants, and another with long implants with bone regeneration. The objective is to evaluate if short-implants are superior in terms of better clinical outcomes, survival rates and safety, reduced surgical time, postoperative discomfort, and complication risk compared to conventional implants and bone regeneration.

Conditions

• Posterior Atrophic Maxilla

Interventions

Type	Name	Description
DEVICE	Ultra short implants	Placement of an ultra short implant of 4mm in the posterior atrophic maxilla without any bone regeneration procedure
DEVICE	Long implants with bone augmentation	Placement of long implants of 8mm in the posterior atrophic maxilla alongside bone augmentation
