| surface of the implant and the crest of the gingiva to select cuff and collar height for the female abutment. This method prevents impingement of the tissue by the male housing. (Fig.3E)
Buccal/Lingual – Mesial/Distal Space Diameter must also be considered. The Locator® metal housings are 5.5 mm wide, and this dimension should be factored in when planning implant site locations. When creating a drilling guide for implants with Locator® abutments the implant centers should be spaced 6.5 mm or more |
apart. In the example in Figure 3F, 4.8 mm platform implants would be spaced 1.7 mm or more interproximally. This leaves 1 mm interproximally between the metal housings.
Locator® Core Tool The three-piece multi-purpose Locator® tool is used to insert the female abutments, remove the processing males (used during the retrofitting step to lock the position of the metal housing inside a denture base) or worn males and insert new nylon males. (Fig.4A) The gold-plated abutment driver has a positive triangle that engages the internal |
