## Indications for use
MIS Ti-base abutment is a titanium base placed onto MIS dental implants to provide support for customized cement-retained or screw retained single or multiple-unit restorations. It is used with a digitally designed mesostructure. MIS Ti-base and the mesostructure make up a two-piece abutment used in conjunction with MIS dental implants, to be placed in the upper or lower jaw arches, in order to restore masticatory function. Narrow platform Ti-bases are indicated for use only in the mandibular central, lateral incisor and maxillary lateral incisor regions of partially edentulous jaws. MIS short implants are to be used only with straight abutments. Mesostructures for use with the MIS Ti-base abutment are to be made from inCoris ZI, designed and manufactured using Sirona CEREC SW version 4.6.1 Software. MIS Ti-base abutments are intended for use with the following MIS implants: C1 conical connection implant system, V3 conical connection implant system, SEVEN internal hex implant system, M4 internal hex implant system and Lance+ internal hex implant system.
