A new insertion technique, pilot-hole preparation, has been developed for proper implant positioning. The purpose of the technique is to prepare pilot holes in positions determined by diagnostic waxup and to form implant channels by means of pilot holes with an instrument called the trephine guide pin. The insertion technique has been shown to be effective for proper implant placement through simulated tests. The advantages of the technique are discussed.
