Long-term Study in Early Loaded Hydrophilic Surface Implants
Study Details
Study Description
Brief Summary
Objective: To assess the clinical outcomes and patient satisfaction of early loaded implants with a hydrophilic, moderately rough surface for partially edentulous patients after a follow-up of 8.5 to 9.5 years.
Materials and methods: A prospective observational single-centre study involving 15 patients with single, delayed placement and early loaded implants in the posterior area was performed. Clinical and radiographical parameters, including biological and technical complications and patient satisfaction, were assessed.

Outcome Measures
Primary Outcome Measures
- Clinical performance - survival [10 years]
Survival was classified as the continued presence of both the implant and reconstruction in the mouth with no need of replacement and/or repair
- Clinical performance - implant success [10 years]
Implant success was classified as the absence of persisting subjective discomfort (patient compliance), lack of recurrent peri-implant infection with suppuration (European Federation of Periodontology 2018), absence of implant mobility on manual palpation, absence of any continuous peri-implant radiolucency at the radiological assessment.
- Clinical performance - prosthetic success [10 years]
Prosthetic success was defined as the absence of technical complications without needing any reconstruction repair.
- Clinical performance - complications [10 years]
A visual exploration of each implant and reconstruction was performed to detect any biological and technical complications.
- Clinical performance - peri-implant health [10 years]
During the clinical follow-up appointments, peri-implant health was evaluated by using a periodontal probe. Periodontal pockets (1-20) All parameters were evaluated mesially, distally, buccally, and orally in each implant; following the EFP guidelines (European Federation of Periodontology 2018).
- Clinical performance - peri-implant health [10 years]
During the clinical follow-up appointments, peri-implant health was evaluated by using a periodontal probe. Plaque index (1-3) All parameters were evaluated mesially, distally, buccally, and orally in each implant; following the EFP guidelines (European Federation of Periodontology 2018).
- Clinical performance - peri-implant health [10 years]
During the clinical follow-up appointments, peri-implant health was evaluated by using a periodontal probe. Bleeding on probing (yes/no) All parameters were evaluated mesially, distally, buccally, and orally in each implant; following the EFP guidelines (European Federation of Periodontology 2018).
- Clinical performance - peri-implant health [10 years]
During the clinical follow-up appointments, peri-implant health was evaluated by using a periodontal probe. Pus (yes/no) All parameters were evaluated mesially, distally, buccally, and orally in each implant; following the EFP guidelines (European Federation of Periodontology 2018).
- Clinical performance - peri-implant health [10 years]
During the clinical follow-up appointments, peri-implant health was evaluated by using a periodontal probe. Keratinized mucosa (mm) All parameters were evaluated mesially, distally, buccally, and orally in each implant; following the EFP guidelines (European Federation of Periodontology 2018).
- Clinical performance - PIBL, implant-crown fit [10 years]
To assess Peri-implant Bone Level (mm), a standardized digital periapical radiograph was taken at the scheduled follow-up visits. An independent examiner performed a radiological linear evaluation (mm) using image analysis software (ImageJ)
- Clinical performance - PIBL, implant-crown fit [10 years]
To assess implant-crown fit (misfit yes/no), a standardized digital periapical radiograph was taken at the scheduled follow-up visits. An independent examiner performed a radiological linear evaluation (mm) using image analysis software (ImageJ)
- Clinical performance [10 years]
Patient satisfaction with the implant treatment was evaluated using a 10 cm visual analogue scale (VAS). From 0 (The worst) to 10 (The best).
