Sequential Healing at Implants with Different Configuration and Modified Surfaces: An Experimental Study in the Dog.

Purpose: To evaluate the peri-implant soft and hard tissue adaptation at implants with different modified surfaces and configurations.

Materials And Methods: Six Beagle dogs were used. Mandibular premolars and first molars were extracted bilaterally.

Sub-crestal positioning of implants results in higher bony crest resorption: an experimental study in dogs.

Objective: To compare peri-implant soft- and hard-tissue integration at implants installed juxta- or sub-crestally. Furthermore, differences in the hard and soft peri-implant tissue dimensions at sites prepared with drills or sonic instruments were to be evaluated.

Material And Methods: Three months after tooth extraction in six dogs, recipient sites were prepared in both sides of the mandible using conventional drills or a sonic device (Sonosurgery(®)).

Healing at implant sites prepared conventionally or by means of Sonosurgery ®. An experimental study in dogs.

Objective: To compare peri-implant tissue healing at implants installed in sites prepared with conventional drills or a sonic device.

Material And Methods: In six Beagle dogs, the mandibular premolars and first molars were extracted bilaterally. After 3 months, full-thickness muco-periosteal flaps were elevated and recipient sites were prepared in both sides of the mandible.

Sequential healing of open extraction sockets. An experimental study in monkeys.

Aim: To describe the sequential healing of open extraction sockets at which no attempts to obtain a primary closure of the coronal access to the alveolus have been made.

Material And Methods: The third mandibular premolar was extracted bilaterally in 12 monkeys, and no sutures were applied to close the wound. The healing after 4, 10, 20, 30, 90 and 180 days was morphometrically studied.

Ridge preservation at implants installed immediately after molar extraction. An experimental study in the dog.

Aim: To evaluate the influence of deproteinized bovine bone mineral (DBBM), in conjunction with a collagen membrane, on bone resorption at implants installed in a lingual position immediately into extraction sockets with horizontal residual buccal defects >2.0 mm.

Material & Methods: The pulp tissue of the mesial roots of (1) M(1) was removed in six Labrador dogs, and the root canals were filled with gutta-percha and cement.

Influence of various implant platform configurations on peri-implant tissue dimensions: an experimental study in dog.

Aim: To evaluate the influence (i) of various implant platform configurations and (ii) of implant surface characteristics on peri-implant tissue dimensions in a dog model.

Material And Methods: Mandibular premolars and first molars were extracted bilaterally in six Labrador dogs. After 3 months of healing, two implants, one with a turned and a second with a moderately rough surface, were installed on each side of the mandible in the premolar region.
