    Abstract: The present invention relates to laboratory components that are used in the field of dental prosthesis and for dental implant fabrication and in particular to a spacer means such as a band, ring, or sleeve forming a soft collar which slips over the analog and slides up to the base of the set impression material near the collar of the impression coping as it emerges through the impression forming a uniform blockout around the impression coping which is recording the sub-gingival space over the top of the fixture and having a soft collar surrounding the neck of the analog insulates the top of the fixture analog from the hard stone where it couples with other components. The spacer forming the soft collar is particularly useful for orienting and indexing the modeling of dental implant restorations and to enhance and improve the fabrication process of soft tissue type models for conventional restoration techniques. It also enhances model techniques for digital scanning of cases in the laboratory.
