- Objective: To evaluate the clinical performance of Astra Tech OsseoSpeed™ TX 3.0S implants using one‐stage surgical procedure and early loading in the anterior region. Material and methods: This is a prospective, single arm, multi‐centre study. Patients missing teeth at positions 12, 22 and 32–42 were eligible to enter the study. The implants (OsseoSpeed™ TX 3.0S) used in the study were of 3 mm diameter and of different lengths. One‐stage surgery was performed, and healing abutments were used during the 6–10 weeks healing period. Clinical and radiographic examinations were assessed at implant installation, loading and at the 6‐ and 12‐month follow‐up visits. Results: Ninety‐seven implants were placed in 69 patients at six different study centres in Denmark, Germany, Italy, Spain, Sweden and the United Kingdom. The survival rate was 95.9%. No implants have been lost after loading (100% survival rate after loading). Mean marginal bone loss 1 year after installation was 0.065 mm (SD = 1.018). The frequency of bone loss ≥1 mm was 6.6% and 51.3% of the implants demonstrated no bone loss or even bone gain from the surgical visit to the first year follow‐up visit. Mean probing pocket depth and gingival zenith score were stable from crown placement to the 6‐ and 1‐year follow‐up visits. Conclusion: Treatment with OsseoSpeed™ TX 3.0S implants is a safe and predictable option in the anterior region where physical space is limited. Minimal marginal bone loss was observed during the first year follow‐up.

- Objective: To determine the dimensions of the soft tissue cuff present at various aspects of teeth and to compare these dimensions to those of the mucosa surrounding single implants. Material and methods: Fifty volunteers were recruited that were ≥25 years of age and exhibited no signs of (i) untreated caries; (ii) loss of periodontal tissue support in the incisor, canine, and premolar regions; (iii) systemic or local disease. Furthermore, among the 50 patients recruited (iV), 27 had one single implant in the maxilla with teeth present mesial and/or distal to the implant. Probing pocket depth (PPD) and transmucosal sounding depth (TS) were assessed by five experienced, carefully calibrated examiners and with the use of a periodontal probe at the proximal (mesial, distal) and flat (facial, buccal and palatal/lingual) surfaces of all teeth/implants. The width of the keratinized mucosa (KM) was also determined. Results: It was demonstrated that (i) PPD and TS were greater at proximal than at flat surfaces at both tooth and implant sites. In addition, both PPD and TS were deeper at implant than at tooth sites. The TS values documented that the cuff of healthy soft tissue that surrounded a tooth varied between 2 mm at flat surfaces and 4 mm at proximal surfaces, while at implant sites, the mucosa at proximal as well as flat surfaces was 1–1.5 mm greater. Conclusion: The probing pocket depth (PPD) and the transmucosal sounding depth (TS) values were greater at proximal than at flat, that is, facial/palatal (lingual) surfaces at tooth sites and frequently also at implant sites. Furthermore, the PPD and the TS dimensions were greater at implant than at adjacent tooth sites.
