A dental implant instrument set for vertically displacing sinus mucosa to form a space for bone augmentation comprises a bone drill and a sinus curette. The bone drill includes a drill bit for drilling upwardly a hole at a site of the alveolar bone where a tooth is lost, so as to expose sinus mucosa. The sinus curette includes a holding portion and a curette head portion. The curette head portion has one end provided with a turning part for separating from the alveolar bone and displacing the exposed sinus mucosa inward through the hole drilled by the drill bit, so as to form a space for bone augmentation above the site of the alveolar bone where the tooth is lost. The turning part is arranged to be at a first angle between 45 to 135 degrees with the curette head portion.

A medical/dental handpiece comprises a housing having distal portion, the head portion having a bottom surface defining an opening. A motor and a light source are positioned with the handpiece, and the handpiece removably receives a light guide in alignment with the light source, to receive light from the light source. The light guide includes a probe which can be positioned adjacent or within a treatment area. The handpiece can be operated to activate only the light source, such that light is directed through the probe to or into the treatment area, to activate only the motor to rotationally or reciprocatingly drive the light guide, or to activate both the light source and the motor.

A set of drill bits and/or burrs for attaching to a hand piece and fitting into an access guide during endodontic access cavity preparation is provided. The drill bits are optionally grouped into two types: a high speed, friction grip attachment type drill bit and a slow speed, latch attachment type drill bit. Each of the drill bits has a different longitudinal length for performing different functions during operation procedures. A method of performing an endodontic access cavity preparation with the set of drill bits is also provided.

A dental surgical drill guide assembly and method includes a surgical guide housing and a base frame that fits to both gum tissue and one or multiple small areas of jawbone. The apparatus may be configured to accurately place dental implants according to planned positions. Such apparatus may increase the stability of the surgical guide by clasping and/or contacting the jawbone, while improving the overall fit and minimizing the need of invasive surgery and flapping by also clasping and/or contacting selected areas of the gum tissue at the same time. Self-locking alignment members aid in easy removal, and re-installation, of the surgical guide housing to the base frame.

A bone foundation guide system and method, the system could includes a bone foundation guide including a body forming an open surgical space, the body further having a bottom contoured to reversibly affix to exposed bone of a dental surgical site and a top contoured to match a bottom side of a dental implant surgical guide; at least one anchoring strut that removably attaches to the body with an apex of the anchoring strut further denoting one or more indentations for matching up with and receiving one or more portions of one alveolar ridge that opposes another alveolar ridge supporting the dental surgical site; alternatively to the anchoring struts and a tissue spacing gasket, the dental implant surgical guide that removably connects to the body; and alternatively to the anchoring struts or the dental implant surgical guide, the tissue spacing gasket that removably connects to the body.

A bone foundation guide system has a bone foundation guide including a body that is contoured to reversibly affix to a bone segment of a dental implant surgical site. The body is further contoured to guide the cutting of a portion of the bone segment from a dental implant surgical site and alternatively support a dental implant surgical guide. The body is further contoured to support a bone foundation guide prosthesis as an alternative to the dental implant surgical guide. The bone foundation guide prosthesis combines with the body to accommodate the bone segment portion as placed through the body prior to the bone segment portion being removed from the dental implant site through the use of the body.

A disclosed method for designing a prosthetic element is executable prior to a cutting of a tooth of a patient for placing the prosthetic element.

Provided is a non-incisional dental implant surgical method, and more particularly, a non-incisional dental implant surgical method using a guide pin, whereby a dental implant surgery may be conducted accurately by easily determining an outer shape of an alveolar bone of a patient, into which an implant fixture is to be placed, when forming an implant hole in the alveolar bone and placing the implant fixture in the implant hole to place an implant in the alveolar bone of the patient.

The present invention relates to a method of determining layer thicknesses (t) of a three-dimensional model (1) for generation with an additive manufacturing apparatus, the method comprising: a step of determining the layer thicknesses (t) according to an adaptive slicing algorithm in which the thickness of a layer (2) is calculated through a relation based on the inclination of the normal vectors (n) of the surface elements (s) of the 3D model (1) which at least partly enclose the layer (2) from a horizontal direction (x; y) the method being characterized by further comprising: a step of selectively imposing on at least one surface element (s) of the 3D model (1) a precision requirement out of one or more selectable different precision requirements which respectively differently alter in the determination step the relation with respect to the inclination of the normal vector (n) of the said at least one surface element (s) which allows, through the altered relation, the layer thickness (t) to obtain a value smaller or larger than the layer thickness (t) determined through the unaltered relation.
