Immedaite vs Early Implant Placement in Aesthetic Area
- Conditions
- Single Implant; Immediate Implant Treatment; Early Implant Treatment
- Interventions
- Device: Implant placement
- Registration Number
- NCT04653025
- Lead Sponsor
- Vilniaus Implantologijos Centro (VIC) Klinika
- Brief Summary
The purpose of this randomized clinical trial, of 50 patients in need of a maxillary anterior implant, was to assess the esthetic outcomes of immediate temporization of immediately placed tapered implants in fresh extraction sockets with soft tissue and bone augmentation as compared to early placed implants with conventional loading. Secondary objectives included the influence of immediate provisionalization on the success rate of tapered implants and crestal bone stability.
- Detailed Description
Patients with a failing maxillary anterior tooth were included in this study. After atraumatic extraction, test group patients received an immediate implant with provisional restoration, while patients in the control group received an implant after 6 weeks of healing. After 4 months (test group) and 6 months (control group) definitive restorations were delivered. All patients were followed for 1 year post restoration and pink esthetic score (PES), mid-buccal mucosal level (MBML), crestal bone changes (CBC) and peri-implant soft tissue parameters were recorded at several time points. In addition, patient chair time was recorded.

- Target Recruitment
- 50
- no recession of gingival contour of tooth to be extracted,
- no periodontal bone loss of neighboring anterior teeth,
- no implants in neighboring teeth,
- class I extraction socket (intact buccal wall),
- atraumatic extraction of the tooth with intact socket walls remaining,
- only one implant per patient to be inserted.
- deep bite (severe II class),
- systemic disease (diabetes, osteoporosis),
- heavy smokers (more than 10 cigarettes/day) were excluded.
- atraumatic extraction of the tooth failed,
- the primary stability (at least 25 Ncm) needed for implant temporization, after implant placement, was not achieved.

Group Intervention Description Test group Implant placement Test group patients received an immediate implant with provisional restoration, bone augmentation and soft tissue grafting Control group Implant placement Patients in the control group received soft tissue grafting after tooth extraction and an implant with bone augmentation after 6 weeks of healing.
- Primary Outcome Measures
Name Time Method Changes of pink aesthetic score (PES) over time Baseline, 1 year and 5 years after prosthetic delivery pink esthetic score means evaluation of seven parameters of anterior tooth aesthetics - mesial and distal papila, soft tissue level, contour, texture, color and convexity. Each parameter may be evaluated by score 0,1 or 2, were the score 0 means the worst outcome, 2 - the best. Evaluation will be performed visually using digital photos.
- Secondary Outcome Measures
Name Time Method Changes of marginal bone level (MBL) around implant neck Baseline, 1 year and 5 years after prosthetic delivery Periapical x-rays will be used to measure crestal bone sability distally and mesially of dental implant using certificated x-ray program after calibration. Measurement will be recorded in millimetres from implant neck to the first bone to implant contact
Recession changes of gingiva of restored tooth on the implant Baseline, 1 year and 5 years after prosthetic delivery Mid-buccal recession evaluation will be performed using standardised periodontal probe. Measurement of the crown hight will be done in the middle of the tooth from incisal edge to the highest point and recorded in millimetres.
