Design outcomes

Primary

MeasureTime frame
The primary outcome of the study will be the evaluation and comparison of marginal bone level changes around implants restored with standard abutment crowns and customised abutment crowns in mandibular molar implant cases. Marginal bone level will be assessed radiographically using standardized intraoral periapical radiographs, measuring the distance from the implant platform to the first bone-implant contact on the mesial and distal aspects of the implant. The measurements will be recorded at baseline and at predetermined follow-up intervals to determine the amount of marginal bone loss and to compare the outcomes between the two groups.Timepoint: Baseline 3 6 and 12th month

Secondary

MeasureTime frame
The secondary outcomes of the study will include the assessment of peri-implant soft tissue esthetics using the Pink Esthetic Score (PES) and the evaluation of patient satisfaction. The Pink Esthetic Score will be used to analyze peri-implant soft tissue parameters such as mesial papilla, distal papilla, soft tissue level, contour, color, and texture around the implant restoration. Patient satisfaction will be assessed using a structured questionnaire or visual analog scale to evaluate factors such as comfort during mastication, esthetic appearance, ease of cleaning, and overall satisfaction with the implant-supported crown. These outcomes will help determine the esthetic and patient-reported differences between standard abutment crowns and customised abutment crownsTimepoint: Baseline 3 6 and 12th month
