Brief Summary

The present study tested the hypothesis that Platform Switching (PS) and Regular Platform (RP) implants would have different outcomes in the bilateral single tooth replacements against the alternative hypothesis of no difference.

Outcome Measures

Primary Outcomes (1)

  • Implant Survival

    implant survival: The removal of implants was dictated by instability, progressive marginal bone loss, infection or implant fracture.

    Up to 12 months

Secondary Outcomes (1)

  • Change in marginal bone levels

    Baseline, 12 months

Other Outcomes (1)

  • Change in peri-implant mucosal response parameters.

    Baseline, 12 months

Study Arms (2)

Implant outcome

OTHER

This study was designed as a randomised, controlled, split-mouth trial. all enrolled patients needed single bilateral fixed implant-supported prosthesis in molar area. A total of 18 consecutive patients were enrolled. In each eligible patient, the right molar was randomly selected to receive either Nobel Replace Tapered Groovy implant; (Nobel Biocare®, Goteborg, Sweden) with Platform Switching (PS) or Regular Platform (RP)

Device: Nobel Replace Tapered Groovy implant; (Nobel Biocare®, Sweden)

OTHER

This study was designed as a randomised, controlled, split-mouth trial. all enrolled patients needed single bilateral fixed implant-supported prosthesis in molar area. A total of 18 consecutive patients were enrolled. In each eligible patient, the left molar was randomly selected to receive either Nobel Replace Tapered Groovy implant; (Nobel Biocare®, Goteborg, Sweden) with Platform Switching (PS) or Regular Platform (RP)

Device: Nobel Replace Tapered Groovy implant; (Nobel Biocare®, Sweden)

Interventions

Both sites received tapered implants with an anodised surface, one site received: Nobel Replace Tapered Groovy PS implant; (Nobel Biocare, Goteborg, Sweden), with diameters of 4.3 or 5.0 mm and lengths of 10 or 8 mm, (PS group), the contralateral site received Nobel Replace Tapered Groovy implant with Replace Select connection with diameters of 4.3 or 5.0 mm and lengths of 10 or 8 mm, (RP group). Healing abutments were connected to implants at the same time of surgery , then flaps were sutured with Vicryl 4.0 sutures (Vicryl, Ethicon J\&J International, St-Stevens-Woluwe, Belgium).

Also known as: Nobel Replace Tapered Groovy PS implant; (Nobel Biocare®, Sweden), Nobel Replace Tapered Groovy implant with Replace Select connection (Nobel Biocare®, Sweden)
