Bone healing at implants with different surface configurations: an experimental study in dogs.

Objective: To study osseointegration of implants with surface modifications by the use of fluoroboric acid and/or H2 O2 installed in conventional sites or sites with circumferential marginal defects.

Material And Methods: Four implants with different surfaces were used. One basic surface (ZirTi(®)) was sandblasted with zirconium microspheres and acid etched additionally with hydrofluoric acid.

Healing at mandibular block-grafted sites. An experimental study in dogs.

Aim: The aim of this study was to evaluate the healing of autologous bone block grafts or deproteinized bovine bone mineral (DBBM) block grafts applied concomitantly with collagen membranes for horizontal alveolar ridge augmentation.

Material And Methods: In six Labrador dogs, molars were extracted bilaterally, the buccal bony wall was removed, and a buccal box-shaped defect created. After 3 months, a bony block graft was harvested from the right ascending ramus of the mandible and reduced to a standardized size.

Influence on alveolar resorption of the buccal bony plate width in the edentulous ridge expansion (E.R.E.)--an experimental study in the dog.

Objective: To compare the hard tissue changes at implants installed applying edentulous ridge expansion (E.R.E.

The edentulous ridge expansion (ERE) technique an experimental study in the dog.

Objective: To compare the healing and bony crest resorption at implants installed conventionally or applying an edentulous ridge expansion (ERE) technique in the maxilla.

Material And Methods: In six Labrador dogs, the first and second maxillary incisors were extracted bilaterally. In the left side of the maxilla (Test), the flaps were elevated and the buccal plate of the alveoli and septa was removed.

Healing outcomes at implants installed in sites augmented with particulate autologous bone and xenografts. An experimental study in dogs.

Aim: To evaluate the integration of implants installed at the interface of pristine and grafted tissue augmented with particulate autologous bone or deproteinized bovine bone mineral (DBBM), concomitantly with a collagen membrane.

Material And Methods: In 6 Labrador dogs, the distal root of (3)P(3) and (4)P(4) was endodontically treated and hemi-sected, and the mesial roots extracted concomitantly with the extraction of (2)P(2). The buccal bony walls were removed, and two box-shaped defects, one larger and one smaller, were created.

Effect of mismatching abutments on implants with wider platforms--an experimental study in dogs.

Aim: To evaluate the effect of mismatching abutments on implants with a wider platform on the peri-implant hard tissue remodeling and the soft tissue dimensions.

Material And Methods: Mandibular premolars and first molars of six Labrador dogs were extracted bilaterally. After 3 months of healing, one tapered implant was installed on each side of the mandibular molar region with the implant shoulder placed at the level of the buccal alveolar bony crest.

Alveolar process preservation at implants installed immediately into extraction sockets using deproteinized bovine bone mineral - an experimental study in dogs.

Aim: To evaluate the soft tissue and the dimensional changes of the alveolar bony crest at sites where deproteinized bovine bone mineral (DBBM) particles, concomitantly with the placement of a collagen membrane, were used at implants installed into sockets immediately after tooth extraction.

Material And Methods: The pulp tissue of the mesial roots of (3) P(3) was removed in six Labrador dogs, and the root canals were filled. Flaps were elevated bilaterally, the premolars hemi-sectioned, and the distal roots removed.

Bone regeneration at implants placed into extraction sockets of maxillary incisors in dogs.

Aim: To compare the influence of autologous or deproteinized bovine bone mineral as grafting material on healing of buccal dehiscence defects at implants installed immediately into the maxillary second incisor extraction socket in dogs.

Material And Methods: In the maxillary second incisor sockets of 12 Labrador dogs, implants were installed immediately following tooth extraction. A standardized buccal defect was created and autologous bone particles or deproteinized bovine bone mineral were used to fill the defects.
