An orthopedic implant having a metal surface and a calcium phosphate layer disposed on at least part of the metal surface is described. The calcium phosphate layer has an average crystallite size of less than about 100 nm in at least one direction and dissolves for more than 2 hours in vitro. The calcium phosphate layer is substantially free of carbonate. The coating, which is formed on a sodium titanate surface, has increased shear strength and tensile strength. The coating is formed by a solution deposited hydroxyapatite process under inert conditions. The pH of the solution varies by less than 0.1 pH unit/hour during coating formation.

A biocompatible composite material for controlled release is disclosed, comprising a biocompatible metal oxide structure with a loaded network of pores. The pore network of the biocompatible composite material is filled with a uniformly distributed biologically active micellizing amphiphilic molecule, the size of these pores ranging from about 0.5 to about 100 nanometers. The material is characterized in that when exposed to phosphate-buffered saline (PBS), the controlled release of the active amphiphilic molecule is predominantly diffusion-driven over time.

Methods for preparing bone void filler substrates with carbonate surface coatings to promote bone growth.

The invention consists of a medical implant for anchoring to the malar process of the maxilla, said implant having a head (1) with an angulation of 35° to 55°; an internal or external connector (2) for different types of abutments; an implant body (3) shaped to define an apical and basal portion, said apical portion being threaded all around, and said basal portion having threads on one side and a faceted canoe-thinning shape on the other side for better layering of soft tissues.

The invention also concerns a medical implant system comprising the aforementioned medical implant, a surgical guide and at least one bone drill.

The invention is suitable for rehabilitation of patients suffering from posterior edentulous maxillae with insufficient bone volume and allows for an immediate rehabilitation of the edentulous patient with a reduced treatment time and morbidity, through a considerably less invasive and technically simplified technique.

This invention relates to the field of medical technology, and can be used in dentistry and traumatology, in particular when creating dental implants. Namely, the invention relates to the development and creation of a method for producing a dental implant characterized by high strength, as well as increased ability to activate the process of osteogenesis and osseointegration. The implant obtained by this method is characterized by high biocompatibility, bactericidal properties (reduces pronounced dystrophic and necrotic processes of living tissue), and an increased level of implant surface strength.
