OBJECTIVES To evaluate and compare the outcome of dental implants placed using a flapless protocol and immediate loading with a conventional protocol and loading after 6 weeks. MATERIALS AND METHODS Fourteen patients with bilateral maxillary edentulous areas were treated using Straumann SLA-implants. Using a randomized split-mouth design, implants were(More)
AIM To detect groups of subjects in a sample of 100 periodontally healthy volunteers with different combinations of morphometric data related to central maxillary incisors and surrounding soft tissues. MATERIAL AND METHODS Four clinical parameters were included in a cluster analysis: crown width/crown length ratio (CW/CL), gingival width (GW), papilla(More)
BACKGROUND Sinus augmentation is a common procedure to increase bone volume and allow for proper implant placement in the atrophic posterior maxilla. Although the patient's own bone is considered the best grafting material, various synthetic or bovine-derived alternatives are used to simplify the grafting procedure. PURPOSE The overall objective of this(More)
BACKGROUND Flapless, free-handed implant surgery offers advantages for patient comfort, but studies on long-term clinical success based on marginal bone loss are scarce. AIM The aim of this study was to compare single implants installed with a flap (F) or flapless (FL) surgery with respect to survival and marginal bone preservation after at least 3 years.(More)
BACKGROUND Implant design and surface may have an influence on the marginal bone response during immediate functional loading. AIM The purpose of this study was to radiographically study the effect of implant design on marginal bone preservation at immediately loaded implants used for prosthetic rehabilitation of the completely edentulous mandible.

PURPOSE (1) To assess validity and reproducibility of mucosal thickness (MT) registration by means of an ultrasonic device and (2) to determine the MT stability of connective tissue grafts (CTGs) when applied at the buccal aspect of single implants demonstrating alveolar process deficiency. MATERIALS AND METHODS For the validity assessment, four human(More)
PURPOSE The objective of this prospective study was to assess the overall outcome of immediate single implant treatment in the anterior maxilla after a 3-year observation period. MATERIAL AND METHODS Thirty consecutively treated patients with a thick gingival biotype, ideal gingival level/contour and intact socket walls at the time of tooth extraction(More)
PURPOSE The primary goal of this study was to compare implant survival 12 months after immediate loading of single implants placed in healed ridges versus extraction sockets. Secondary outcomes were to compare marginal bone adaptation and soft tissue changes over time. MATERIALS AND METHODS A prospective multicenter clinical investigation was initiated to(More)
This retrospective study focuses on patient opinion and professionally assessed quality of single-tooth restorations of Brånemark fixtures. Patients were treated by periodontists for fixture installation and/or abutment connection and by referring general practitioners for prosthetic rehabilitation. Seventy-eight consecutively treated patients were sent a(More)
AIM The purpose of this prospective multicenter clinical study was to compare 3 years implant survival, bone and soft tissue changes following immediate loading using single Osseospeed(™) implants (Astra Tech AB, Mölndal, Sweden) installed in healed ridges or extraction sockets. MATERIAL AND METHODS Implants were provisionally restored the day of surgery(More)
