Bone Loss Clinical Trial
Official title:
Effect of Bone-related and Soft-tissue-related Variables on the Marginal Bone Loss of Platform-matched and Platform Switched Dental Implants
In this clinical trial the effect of the implant-abutment morphology (platform-switched vs platform matched) will be assessed in both soft tissue (soft tissue thickness) and hard tissue (marginal bone loss) outcomes. Several clinical predictors (initial implant position level, gingival biotype, abutment height and prosthetic emergence profile) will also be taken into account as modulating factors of the clinical outcome.

Eligibility | Inclusion Criteria: - Patients of legal age (>18 years). - With rehabilitation needs with 1 maxillary or mandibular implant in mature bone (more than 4 months after tooth extraction) in the posterior sector (premolars and molars). - With good hygiene (plaque and gingival index = 25%). Exclusion Criteria: - Medical conditions that contraindicated implant surgery. - Patients with immunological alterations, pregnant and lactating. - Heavy smokers > 20 cigarettes/day, - Requiring bone augmentations or of soft tissues. - Patients whose anatomy prevented the correct three-dimensional placement of the implant to perform prosthetically guided screw-retained restorations. |

Primary | Change in the Peri-implant Marginal Bone level | The implant-bone level is assesssed radiographicly | At baseline (reference), in comparison with 3, 6 and 12 months | |
Primary | Change in the Implant stablity quotient | The ISQ is assesssed by Osstell | At baseline (reference), and in comparison with the 3 months follow-up | |
Primary | Change in the Gingival Thickness | The gingival thickness will be assessed by measuring the keratinized region around implants with a periodontal probe and a thickness caliper | At baseline (reference) and in comparison with the 3, 6 and 12 months follow-up |
