Abstract
Purpose: To evaluate implant and prosthetic survival rates, complications, patient satisfaction, and biological outcomes of patients rehabilitated with a ball attachment system for implant retained- and supported-overdentures (IOV), which was in function for 3 to 5 years. Methods: This retrospective study evaluated data collected from patients treated between April 2001 and May 2018 with IOV on splinted and non-splinted implants and a ball attachment system. Patients were followed for 36 to 206 months (mean follow-up was 128.1 ± 51.9 months). Data were collected at the 3- and 5-year follow-up examination. Outcome measures were implant and prosthetic survival rates, technical complications, marginal bone loss (MBL), oral health impact profile (OHIP), and periodontal parameters (bleeding on probing and plaque index). Results: A total of 46 patients (16 males and 30 females) with 124 implants were included in this study. Twenty-five implant-retained overdentures were delivered on 53 unsplinted implants, while the other 21 patients received an implant-supported overdentures and the implants were splinted. At the five-year follow-up examination, one implant and one prosthesis failed in the unsplinted group, resulting in a cumulative survival rate of 97.8% at the patient level. Two minor technical complications were experienced. Conclusions: Implant overdenture retained or supported by ball attachment systems showed high implant and prosthetic survival and success rates. A low number of complications, high patient satisfaction, and successful biological parameters were experienced in the mid-term follow-up. Data need to be confirmed by further randomized trials.

A retrospective chart review of existing data, documents, radiographs, and digital files was performed at one center in Italy to evaluate data collected from fully edentulous patients treated between April 2001 and May 2018
Summary
Edentulism is defined as “the state of being without any natural permanent teeth. J. 2019, 7, 84 reduction in masticatory function. Because of this behavior the risk of cardiovascular diseases and gastrointestinal disorders may increase [2]. Phonetic and speech functions are affected after the loss of anterior teeth, making edentulous patients less confident and limited to interacting with other people [3,4]. Trying to solve these problems, in these cases, dental implants can be invaluable
