An anchor to be screwed into a hole with high primary stability and eventually even higher secondary stability. A right hand thread form winds with continuous turns along the body of the anchor. A trailing flank of the thread form is back-angled. The central region includes an array of flutes having left-hand helical twist. Each flute is composed of distinct flute segments. A condensing ramp is formed along the crest of the thread form between two circumferentially—adjacent flute segments. Each condensing ramp is pitched about 20° so as to apply a localized compressive strain to the interior surface of the host bone with a densifying action when the anchor is screwed into the prepared hole. The condensing ramps create induced stress and super-activated zones in the bone directly adjacent to healing chambers formed by the flute segments. The healing chambers draw bone to naturally encourage and promote healing.

There is provided in accordance with an exemplary embodiment of the invention a method of osteointegration of an implant into surrounding jaw-bone, the method comprising: applying a magnetic field around an implant, the magnetic field produced around the implant to a jaw-bone depth of up to at least about 7 mm, the magnetic field having a magnetic flux density of about 0.05-0.5 mT at up to at least about 2 mm from a surface of the implant, the magnetic field produced by a coil within the implant. A device adapted for insertion into a jawbone implant and for producing the magnetic field for bone enhancement of surrounding jawbone is also described.

A special tube is disclosed for the insertion of materials inside the maxillary sinus in order to displace the Schneiderian membrane. The tube is connected to a source of a flowable material. The tube is inserted through the alveolar ridge beneath the maxillary sinus and when the flowable material is advanced through the tube the Schneiderian membrane is lifted. The tube can be part of a dental implant which is screwed inside the alveolar ridge.

An endosseous dental implant assembly includes a dental implant including an abutment portion for connecting to a tooth crown and a hollow base portion defining a cavity therein, and a bio-supportive or biodegradable scaffold carried by the hollow base portion of the dental implant in the biomimetic approach. The abutment portion is formed integrally with the hollow base portion. The scaffold is impregnated with regenerative stem cells, growth factors, biomorphic proteins, or autogenous cells. In the osseointegrated approach, bone graft material can be carried to the extraction socket without a scaffold.

Apparatus is provided that includes a surgical tool for use with solid particles and a physiological liquid solution. The surgical tool includes (a) a shaft unit, which is shaped so as to define a delivery lumen, and a distal opening, which is disposed within 10 mm of a distal end of the shaft unit, in fluid communication with the delivery lumen; (b) a composition source, which is coupled in fluid communication with the delivery lumen, and which is configured to provide a solid-liquid composition of the solid particles and the physiological liquid solution; and (c) a pump, which is configured to pump the solid-liquid composition through the distal opening via the delivery lumen.

An implant fixture is disclosed. The implant fixture contains an elongated shaft section, a head section, wherein the head section comprises at least one concave area for bone growth therein, and a protrusion extending from the head section.

A porous, resorbable and flexible dental surgical membrane (16) is made from chitosan having a viscosity average molecular weight of about 400,000 daltons up to about 2,000,000 daltons and has a thickness of from about 100 microns to about 0.5 mm. The membrane is easily insertable over a bone graft material site to confine the bone graft material (14) while allowing access to the bone graft material of blood and oxygen and applied medicaments through the membrane. The high molecular weight of the chitosan may be chosen so that the membrane will not dissolve or resorb in a human mouth for a protracted period, e.g., from about 12 to about 16 weeks. The membrane is made by dissolving medical grade chitosan in aqueous acetic acid, dispersing fine silica particles into the solution to form a slurry, depositing a film of the slurry on a support surface, evaporating liquid from the slurry sufficiently to form a coherent chitosan membrane having silica particles dispersed therein, and then dissolving the silica particles with a sodium hydroxide solution followed by a water wash to form the porous chitosan membrane.

There is a need for a minimally invasive surgical treatment method for periodontitis for the removal of deep pockets, elimination of disease, creation of reattachment of the gingiva to the tooth surface and true regeneration of the attachment apparatus (new cementum, new periodontal ligament, and new alveolar bone) on a previously diseased root surface. The PerioLase® MVP-7™ including eGUI or another device capable of laser dosimetry, such as an original MVP-7™ type laser without the eGUI, achieves this with the LANAP protocol (laser-assisted new attachment procedure) and the LENAP protocol (laser excisional new attachment procedure).

Embodiments described herein are related to pellets that are placed within an extraction site that is in need of bone augmentation and preservation. The pellets are typically cylindrical in shape and comprise a material and a polymer coating. The goal of the pellets are to encourage sufficient new bone growth that jaw bone deterioration is prevented. The pellets create, arrange, and assemble an ideal growth environment for new bone growth to rapidly grow and preserve the original contours of an individual's jaw bone.
