Peri-implantitis at implants with different diameters: a pilot study in dogs.

Aim: To evaluate the progression of an induced peri-implantitis at implants with different diameters and the outcome of a corrective surgical debridement.

Methods: Three months after the extraction of the mandibular premolars and first molars in six dogs, non-submerged narrow implants (3.3 mm in diameter) or standard implants (3.

Influence of bone marrow on osseointegration in long bones: an experimental study in sheep.

Aim: To evaluate the influence of yellow bone marrow on osseointegration of titanium oral implants using a long bone model.

Material And Methods: The two tibiae of eight sheep were used as experimental sites. Two osteotomies for implant installation were prepared in each tibia.

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.

Bone-healing pattern at the surface of titanium implants: an experimental study in the dog.

Objective: To study the early sequential stages of osseointegration at implants installed in alveolar bony.

Materials And Methods: In 12 Labrador dogs, all mandibular premolars and first molars were extracted bilaterally. After 3 months of healing, full-thickness flaps were elevated in the edentulous region of the right side of the mandible.

Connective tissue grafts in conjunction with implants installed immediately into extraction sockets. An experimental study in dogs.

Aim: To evaluate the influence of a sub-epithelial connective tissue graft placed at the buccal aspect of implants installed immediately after tooth extraction on the dimensional changes of hard and soft tissues.

Materials And Methods: In six Labrador dogs a bilateral partial- thickness dissection was made buccal to the second mandibular premolar. At the lingual aspect, full-thickness flaps were elevated.

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.

Behavior of aqueous nanocrystalline hydroxyapatite in oral bone regeneration.

Purpose: A skeletal segment consisting exclusively of bone is the target outcome of bone regeneration. Granular hydroxyapatites form a hydroxyapatite-bone composite, unsuitable for effectively supporting implants, which may persist for many years. This work aimed to investigate the reasons for the bone replacement of Ostim®, a recently commercialized aqueous nanocrystalline hydroxyapatite.
