exhibitors 14 Hinman Dental Meeting — March 18, 2016 By Timothy Kosinski, DDS, MAGD n Maxillary lateral incisor agenesis (MLIA) is a congenital condition in whichatleastoneofthemaxillarylat- eralincisorsismissingintheprimary or permanent dentition. MLIA occurs in the smile zone and affects esthet- ics and function.1,2 Although MLIA may present challenges because of limited space, implant therapy has becomeoneoftheprimaryoptionsfor addressing it.3 For patients with MLIA, implant therapy is a conservative approach that avoids damage to the neighbor- ing dentition.1 Treatment is relatively noninvasive because adjacent teeth do not need to be prepared. If there is not enough room for an implant, it is possible to create space through orthodontics.4 The following case summary dem- onstrates implant placement in a 20-year-old female who presented with an acid-etch bridge used to restore her missing maxillary right lateral incisor. Although esthetic, the bridge fell off periodically. Because of problems with long-term retention, the acid-etch bridge is not considered a viable permanent solution.5 The patient was interested in implant treatment. The Hahn™ Tapered Implant System (Glidewell Direct; Irvine, Calif.) was utilized to restore the missing tooth. A cement- retained BruxZir® Anterior crown provided a strong, esthetic final result. Case summary The patient presented with a cuspid and central incisor that were mini- mally prepared to support an acid- etch bridge. The bridge was esthetic, but the patient was concerned about long-term function (Fig. 1). The lateral incisor site can present difficulties when surgically plac- ing dental implants. Radiography indicated, however, that there was enough space for an implant. Scans were taken using the PaX-i3D Green imaging system (VATECH America Inc.; Fort Lee, N.J.). Because the patient’s anatomy did not present any complications, the implant was placed freehand. The diameter of the osteotomy was slightly smaller than that of the implant chosen for this case, and a depth of approximately 13 mm was established. A 3-mm-diameter Hahn Tapered Implant was utilized. The diameter size and tapered body of the implant was ideal for the limited space. The implant features prominent threads, which eases placement and allows the clinician to thread the implant into an undersized osteotomy. The abilitytoplaceanimplantinaslightly smaller osteotomy can help ensure excellent primary stability.6 A cover screw was hand-tightened into the implant. The patient’s acid- etch bridge was cemented back onto the adjacent teeth and functioned as a transitional appliance during heal- ing. Four months following surgery, the patient returned to begin the restorative process (Fig. 2). A tissue punch was utilized to access the healed implant site. Panasil® vinyl polysiloxane mate- rial (Kettenbach; Huntington Beach, Calif.) was used to create a final impression. The dental lab fabricated an Inclusive® Titanium Custom Abut- ment and a BruxZir Anterior crown. Because the patient could only return to the dental office during school breaks, she again used the bridge as a transitional prosthesis. At the final delivery appoint- ment, the custom implant abutment was placed and the final crown was cemented on the custom abutment. The patient was pleased to have a fixed restoration that exhibits high stability, strength and esthetics (Fig. 3). Conclusion Implant treatment proved to be an outstanding treatment modality in a difficult situation. The Hahn Tapered Implant allowed for surgical predict- ability and reliable osseointegration.

Here in Atlanta To learn more about the Hahn Tapered Implant, stop by the Glidewell Labora- tories booth, No. 1712. n TAUB Products, a long-time manufacturer of dental consumable products, announced the release of Liquid Magic Resin Barrier for implant and cosmetic dentistry. Liquid Magic is a light- cured resin used to protect threading, screws and internal components of implants and abutments. Used prior to the placement of a crown, Liquid Magic works in conjunction with ZERO-G Bio- Implant Cement, resulting in better seating of the crown and easier cleanup. Taub also announced a new breakthrough in base/liner materials with the release of Ca-Lok Flowable Adhesive Calcium Base/Liner. Ca-Lok is a light-cured, calcium-filled resin with adhesive properties to dentin and seamless compatibility to other restorative materials. Ca-Lok is radiopaque and releases fluoride. Ca-Lok is used as a protective liner and can be placed under restorative materials and cements for all deep cavity preparations. To check out Liquid Magic and Ca-Lok, stop by the booth, No. 509, here at the Hinman Dental Meeting or go online to www.taubdental.com.
