It was reported in the literature that patients with prematurely exposed cover screws suffered 3.9 times greater bone loss than nonexposed ones.37 Quantity of keratinised tis- sue Adequate keratinised tissue may be more important around implants than natural teeth for several reasons: supracrestal collagen fibers are oriented in a parallel rather than in a perpendicular configuration adjacent to transmucosal sur- faces of implants38 , providing less resistance to local trauma and microbial penetration. Periimplant mucosa may have a reduced capacity to regener- ate itself due to compromised number of cells and poor vas- cular suply.39 Oral hygiene, smoking, alcohol abuse Patients with poor oral hygiene and/or existing periodontal disease experience greater per- iimplant crestal bone loss than patient with good oral hygiene and stable periodontal sta- tus. Both current and lifetime cigarette are associated with deterioration in bone qual- ity and impaired wound heal- ‘Premature expo- sure of an implant cover screw through the overlying mucosa may result where mucosal tissues fail to achieve primary closure’ OsseoSpeed™ TX Profile – anatomically designed implants for sloped ridges Imagine being able to achieve 360° bone preservation around the implant, even in cases with sloped ridges.
