Immediate loading implants with mandibular overdenture: a 48-month prospective follow-up study

Abstract

The aim of this prospective clinical study was to evaluate patient rehabilitation with two immediately loaded implants and bar-retained mandibular overdentures after 48 months of follow-up. Twenty patients were treated with two implants each; of these, 17 patients were re-evaluated for comparison. Gender, age, plaque index, gingival inflammation, keratinized mucosa, probing depth, bleeding, and implant loss data were recorded, and periapical radiographs were obtained for measurement of marginal bone loss. The results were statistically analyzed with one-way analysis of variance (ANOVA) followed by Student's t-test and Pearson's correlation test. To compare the data at baseline and after 48 months, a Wilcoxon Signed Rank Test was performed (α = 0.05). One implant failed (2.9%) during the first year and was replaced. A total of 35 implants were evaluated. Bone loss values were 0.52-2.89 mm (mean, 1.46 mm). Probing depth was 1.75-3.75 mm (mean, 2.22 mm). Correlations were found between bone loss and plaque index and between bone loss and gender, but bone loss did not correlate with gingival inflammation, keratinized mucosa, probing depth, or age. The overall survival rate of the implants was 97.1%. Based on these results, the use of two immediately loaded splinted interforaminal implants to retain an overdenture with a bar attachment is a clinically viable option with a high survival rate.

Three-year Prospective Evaluation of Immediately Loaded Mandibular Implant Overdentures retained with Locator Attachments

“…An implant length of at least 13 mm was placed, as a minimum acceptable implant length of 10 mm was considered viable by some authors when immediate loading protocol is to be attempted. 52,53 Care was also taken to ensure primary stability of implants before being immediately loaded. The primary stability is a crucial factor that determines the long-term success of dental implants.…”

“…One of them is the immediate implant technology, which shortens the course of treatment for implantation 14) . Nevertheless, a sufficient amount of bone mass and a good quality of sclerotin is necessary for the application of this technique.…”

“…La cirugía implantológica es una técnica predecible y muy utilizada en odontología (16)(17)(18). En la literatura se refleja que el dolor asociado a la técnica, todo y que se lesionan los tejidos orales para su inserción es discreto (19), dependiendo entre otros aspectos de la predisposición del paciente frente al mismo (20).…”
