  1. 1. On titanium release from dental implants and the inflammatory response

    Författare :Mattias Pettersson; Margareta Molin Thorén; Anders Johansson; Ann Wennerberg; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; titanium; inflammation; dental implants; peri-implantitis; odontologi; Odontology;

    Sammanfattning : In dentistry, dental implants have become a standard treatment for single tooth loss and partial and total edentulism since their introduction by P-I Brånemark in the 1960s. Long-term follow-up studies have shown that dental implantation is a predictable treatment, with an overall implant survival over ninety-five percent. LÄS MER

  2. 2. On the tissue response to hafnium, titanium and thin calcium phosphate coatings

    Författare :Sham Mohammadi; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICAL AND HEALTH SCIENCES; hafnium; titanium; calcium phosphates; hydroxyapatite; implants; bone; soft tissue; histomorphometry;

    Sammanfattning : Background: Titanium (Ti) is the gold standard material for load-bearing implants. Although high success rates have been reported for Ti implants, failures do occur. Alternative materials/surface modifications might further improve the performances of Ti implants, particularly in situations with non-optimal local tissue conditions. LÄS MER

  3. 3. Soft tissue integration to dental implants

    Författare :Maria Welander; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; connective tissue; dental implants; epithelium; gold alloy; histology; peri-implant mucosa; subcrestal placement; titanium; zirconia;

    Sammanfattning : Soft tissue integration is a prerequisite for implant success. The role of the soft tissue barrier at implants is to provide an effective seal that protects the underlying bone and prevents access for microorganisms and their products. LÄS MER

  4. 4. On the influence of micro-and macroscopic surface modifications on bone integration of titanium implants

    Författare :Patricia Miranda Burgos; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :titanium; dental implants; surface modification; bone tissue; biomechanics; BMP-2;

    Sammanfattning : Background: Osseointegrated titanium implants are routinely used in clinical denstistry as anchorage units for dental prostheses. Although the overall clinical results are good, there are clinical situations when an optimized implant healing is desirable, for instance in order to shorten healing periods and to allow immediate loading.

  5. 5. On the Bone Tissue Response to Surface Chemistry Modifications of Titanium Implants

    Författare :Byung-Soo Kang; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Osseointegrated titanium implants; Magnesium and Calcium Incorporated Bioactive Titanium Oxide; Metal Plasma Immersion Ion Implantation and Deposition; Micro Arc Oxidation; Clinical Implants; In Vivo Bone Response;

    Sammanfattning : Background: Surface properties of titanium implants play an important role in osseointegration. From 1990, a lot of engineering techniques have been applied to dental implant productions for improving their clinical performance by changing surface properties. LÄS MER
