An improved method of a dental framework design and manufacturing, incorporating a dental framework design volume to eliminate framework or denture teeth modification post framework manufacturing.

A dental implant assembly comprising an elongated inner body substantially resembling a tooth root (1-1) and an outer member for securing to a bone of a patient (1-2) having a heterogeneous porous structure adapted to provide bone growth, the inner body and the outer fixation member being formed in one piece, the fastening element being movable between a stored passive position and an extended active position (1-2).

A gutta-percha-silver composite with determined weight percentage and particle size, is provided. The composite exhibits electro-conductivity greater than the standard gutta-percha composites. The new material simplifies root canal treatments, shortens the times both for clinician and patients, and reduces the exposure to patients from X-rays. The material is not only electro-conductive; it is anti-bacterial, which improves the outcomes of the procedures. Also, it has improved thermal conductivity, and mechanical properties.
