Clinical and histological comparison of the soft tissue morphology between zirconia and titanium dental implants under healthy and experimental mucositis conditions—A randomized controlled clinical trial

Objectives To analyse the soft tissue morphology under healthy and experimental mucositis conditions comparing zirconia and titanium implants. Methods Forty‐two patients with two adjacent missing teeth received one zirconia (Zr) and one titanium (Ti) implant, with the mesial and distal position rand...

description Objectives To analyse the soft tissue morphology under healthy and experimental mucositis conditions comparing zirconia and titanium implants. Methods Forty‐two patients with two adjacent missing teeth received one zirconia (Zr) and one titanium (Ti) implant, with the mesial and distal position randomized. At 3 months, half of the patients were instructed to continue (healthy; h) and the other half to omit (experimental mucositis; m) oral hygiene around the implants for 3 weeks. Clinical parameters were evaluated before and after the experimental phase, and a soft tissue biopsy was harvested. Mixed model analyses were performed to analyse the data. Results The plaque control record increased significantly for the two mucositis groups, reaching 68.3 ± 31.9% (mean ± SD) for Zr‐m and 75.0 ± 29.4% for Ti‐m (p

Bleeding on probing remained stable in group Zr‐m and amounted to 21.7 ± 23.6%, but increased significantly in group Ti‐m (p = .040), measuring 32.5 ± 27.8%. The number of inflammatory cells and the length of the junctional epithelium did not significantly differ between the groups. Conclusion Both implants rendered similar outcomes under healthy conditions. Lower plaque and bleeding scores were detected for zirconia implants under experimental mucositis conditions. Histologically, only minimal differences were observed.</description><identifier>ISSN: 0303-6979</identifier><identifier>EISSN: 1600-051X</identifier><identifier>DOI: 10.1111/jcpe.13411</identifier><identifier>PMID: 33278048</identifier><language>eng</language><publisher>United States: Blackwell Publishing Ltd</publisher><subject>Biopsy ; Bleeding ; Clinical trials ; Dental implants ; Dental Implants - adverse effects ; Dental prosthetics ; Dentistry ; Epithelium ; histology ; histomorphometry ; Humans ; Hygiene ; Inflammation ; Morphology ; Mucositis ; Oral hygiene ; peri‐implant soft tissue ; Titanium ; Transplants &amp; implants ; Zirconia ; zirconia implant ; Zirconium</subject><ispartof>Journal of clinical periodontology, 2021-05, Vol.48 (5), p.721-733</ispartof><rights>2021 John Wiley &amp; Sons A/S.
