Prospective randomized clinical trial evaluating the effects of two different implant collar designs on peri-implant healing and functional osseointegration after 25 years.

Objectives: Evaluate the effects of two different machined-collar lengths and designs on peri-implant healing.

Material And Methods: An implant with a microtextured surface and 3.6mm-long internal-connection machined collar was compared to two implants that had an identical 1.

Axolotl as a Model to Study Scarless Wound Healing in Vertebrates: Role of the Transforming Growth Factor Beta Signaling Pathway.

Significance: The skin is our largest organ, with the primary role of protection against assaults from the outside world. It also suffers frequent damage, from minor scrapes to, more rarely, complete destruction such as in third-degree burns. It is therefore, by its nature, an organ that would benefit tremendously from being able to regenerate itself.

Preservation of posterior mandibular extraction site with allogeneic demineralized, freeze-dried bone matrix and calcium sulphate graft binder before eventual implant placement: a case series.

Objective: This case series reports short- and long-term healing, before and after placement of an implant, in posterior mandibular extraction sites grafted with demineralized, freeze-dried bone matrix (DFDBM) allograft mixed with calcium sulphate graft binder.

Methods: Three patients who underwent surgical extraction of a posterior mandibular molar experienced partial loss of the buccal bone plate at the extraction site. Alveolar bone reconstruction with a DFDBM allograft mixed with calcium sulphate graft binder was performed immediately.
