An anatomically dimensioned healing cap is provided for use during second stage surgery of a dental implant which preserves the actual tooth contour within the gingiva to facilitate accurate crown reproduction exhibiting a proper emergence profile. The healing cap has a housing that is dimensioned in accordance with the removed tooth and has a releasably securable insert that directly engages the head of any implant without scoring or damaging the implant. For posterior teeth, the healing cap can preserve the tooth cavity in the gingiva tissue even if the implant is mounted off-center of the original tooth location. The healing cap also provides an occlusal lip to prevent the overgrowth of gingiva tissue during second stage healing. Plastic burnout sleeves and cylinders are provided to enable dental technicians to more accurately and more efficiently create a crown or bridge. Healing cap models and an implant alignment indicator are provided to enable the dental surgeon to more accurately locate and align a dental implant in the initial stages of surgery.
A healing cap to be used in a predetermined position in the gingiva tissue of a patient during second stage surgery of a dental implant for mounting a crown replicating a tooth naturally residing at the position, the implant having a head with an anti-rotational coupling, said healing cap forming a cavity in the gingiva tissue, when installed in a patient's mouth whose shape replicates a portion of the tooth and comprising a housing and an insert, said housing having an outer surface including portions having at least two predetermined dimensions, said dimensions comprising the mesio-distal dimension of the neck of the tooth and the labio-lingual dimension of the neck of the tooth, said dimensions being representative of the anatomical dimensions of the corresponding portions of the tooth which was located within the gingiva tissue, said insert having coupling means to engage and mate with the anti-rotational coupling on the head of the dental implant, the anti-rotational coupling forming the opening to a threaded bore, said insert being releasably secured inside said housing by a securement means, said housing, said coupling means being adapted to be aligned with the anti-rotational coupling of the dental implant and further comprising a retaining screw passing through said housing and said insert and adapted to engage the dental implant, said retaining screw releasably adapted to secure said healing cap against the head of the dental implant.
A system for creating a crown which replicates a tooth naturally residing at a predetermined position in the gingiva tissue of a patient, said crown being arranged for securement to a dental implant having a head including an antirotational coupling, said system comprising a healing cap, said healing cap forming a cavity in said gingiva tissue when installed in a patient's mouth whose shape replicates a portion of the tooth and comprising a housing and an insert, said housing having an outer surface including portions having at least two predetermined dimensions, said dimensions comprising the mesio-distal dimension of the neck of the tooth and the labio-lingual dimension of the neck of the tooth, said dimensions being representative of the anatomical dimensions of the corresponding portion of the tooth which was located within the gingiva tissue, said insert having coupling means to engage and mate with the anti-rotational coupling on the head of the dental implant, the anti-rotational coupling forming the opening to a threaded bore, said insert being releasably secured inside said housing by a securement means, said housing, said coupling means being adapted to be aligned with the anti-rotational coupling of the dental implant and further comprising a retaining screw passing through said housing, and said insert and the dental implant, said retaining screw adapted to releasably secure said healing cap against the head of the dental implant.
