Armi e interventi
Gruppo di partecipanti / Arm |
Intervento / Trattamento |
|---|---|
|
Sperimentale: Arm 1: Denture A with Locator ST Participants receive Denture A retained by Locator ST attachments.
Participants receive Denture A retained by Locator ST attachments.
|
Participants receive Denture A, a conventional mandibular implant overdenture, retained by two Locator ST attachments placed in the interforaminal region.
Outcomes include OHIP-19, VAS satisfaction, retention force, attachment wear, periodontal parameters, and denture tooth wear resistance.
|
|
Sperimentale: Denture A with Locator EMI
Participants receive Denture A retained by two Locator EMI attachments.
Same outcome measures as above, allowing comparison of attachment type influence on patient-reported and clinical outcomes.

Cosa sta misurando lo studio?
Misure di risultato primarie
Misura del risultato |
Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Retention Force of Implant Overdentures (IODs)
Lasso di tempo: Outcome measures were assessed at four clearly defined time points: 1. Baseline (Immediately after overdenture pick up) 2. 3 month follow up 3. 6 month follow up 4. 9 month follow up These time points correspond to the evaluation of implant overdentures
|
Retention force measured using a digital force gauge to quantify the dislodgement force required to remove the overdenture from the implants.
Measurements will be reported in Newtons (N).
|
Outcome measures were assessed at four clearly defined time points: 1. Baseline (Immediately after overdenture pick up) 2. 3 month follow up 3. 6 month follow up 4. 9 month follow up These time points correspond to the evaluation of implant overdentures
|
|
Denture Wear of Implant Overdentures (IODs)
Lasso di tempo: Wear was evaluated relative to the baseline measurement taken immediately after pick-up, with follow-up assessment 9-month per denture type: 1. 3 month follow up 2. 6 month follow up 3. 9 month follow up
|
Denture wear assessed by measuring surface loss on occlusal surface using digital analysis.
Wear depth recorded in millimeters (mm) at each evaluation point.
|
Wear was evaluated relative to the baseline measurement taken immediately after pick-up, with follow-up assessment 9-month per denture type: 1. 3 month follow up 2. 6 month follow up 3. 9 month follow up
|
|
Peri-implant Soft Tissue Health (Modified Plaque Index and Modified Bleeding Index Scores)
Lasso di tempo: Assessments performed over an 18-month total follow-up period, at the following intervals: 1 - Immediately after pick-up (baseline) 2 - 3 months 3 - 6 months 4 - 9 months 5 - 12 months 6 - 15 months 7 - 18 months
|
Peri-implant soft tissue health assessed using the Modified Plaque Index (mPI) and Modified Bleeding Index (mBI). Both indices are ordinal clinical scales scored according to standard peri-implant evaluation criteria: mPI range: 0-3 0 = no plaque 3 = abundant plaque mBI range: 0-3 0 = no bleeding 3 = profuse bleeding Interpretation: Higher scores indicate worse peri-implant soft tissue health. Unit of Measure: Ordinal index scores (mPI, mBI) |
Assessments performed over an 18-month total follow-up period, at the following intervals: 1 - Immediately after pick-up (baseline) 2 - 3 months 3 - 6 months 4 - 9 months 5 - 12 months 6 - 15 months 7 - 18 months
|
|
Crestal bone level changes
Lasso di tempo: Radiographic measurements performed over an 18-month total follow-up period, at the following intervals: 1 - Immediately after pick-up (baseline) 2 - 3 months 3 - 6 months 4 - 9 months 5 - 12 months 6 - 15 months 7 - 18 months
|
Crestal bone levels measured on standardized periapical radiographs taken with a paralleling technique.
Bone level is defined as the distance from the implant shoulder to the first bone-to-implant contact.
|
Radiographic measurements performed over an 18-month total follow-up period, at the following intervals: 1 - Immediately after pick-up (baseline) 2 - 3 months 3 - 6 months 4 - 9 months 5 - 12 months 6 - 15 months 7 - 18 months
|
|
Oral Health-Related Quality of Life (OHIP-19 score)
Lasso di tempo: OHIP-19 scores recorded three times during each 9-month denture phase: 1 -Before pick-up 2 - Immediately after pick-up 3 - At 9 months follow up
|
Oral health-related quality of life assessed using the Oral Health Impact Profile-19 (OHIP-19) questionnaire. The OHIP-19 consists of 19 items, each scored on a 5-point ordinal scale from 0 to 4: 0 = never 4 = very often Minimum score: 0 Maximum score: 76 Interpretation: Higher scores indicate worse oral health-related quality of life. |
OHIP-19 scores recorded three times during each 9-month denture phase: 1 -Before pick-up 2 - Immediately after pick-up 3 - At 9 months follow up
|
|
Patient Satisfaction (Visual Analog Scale Score)
Lasso di tempo: VAS satisfaction scores recorded three times during each 9-month denture phase: 1 - Before pick-up 2 - Immediately after pick-up 3 - At 9 months follow up
|
Patient satisfaction with the denture and attachment system measured using a 10-point Visual Analog Scale (VAS). Participants rated their satisfaction on a scale from 0 to 10: 0 = completely dissatisfied 10 = completely satisfied |
VAS satisfaction scores recorded three times during each 9-month denture phase: 1 - Before pick-up 2 - Immediately after pick-up 3 - At 9 months follow up
