Case report In a 66-year-old male patient, the crown of tooth #22 was fractured (Fig. 1). The tooth had been endodontically treat- ed with insertion of an abut- ment post and crown about 15 years previously. The patient had no pain and there were no periapical abnormalities. However, in view of the slen- der root, a new post and crown did not appear advisable (Fig. 2). Because the patient did not want the neighbouring teeth ground (“I want a new lateral incisor. I certainly don’t want the healthy neighbouring teeth ground”), only an implant came into consideration. The panoramic radiograph showed incomplete filling of the root remnants, a general- ised horizontal bone defect and endodontic and dental restora- tions in all four quadrants (Fig. 2). The pocket depth was nei- ther unremarkable at 3 to 3.5 mm, nor was there bleeding on probing. The periodontitis was evidently accompanied by tis- sue recession, largely without pocket formation or acute in- flammation. The soft tissue was somewhat rough and was clas- sified as belonging to the ‘thick’ phenotype. Other findings were periodontitis originating from the pulp of tooth #45, an im- plant at position 44, tooth #37 inclined strongly into gap 36 and a retained tooth #38. There were no functional abnormali- ties. The patient did not smoke and, apart from pharmacologi- cally controlled hypertension, was healthy. As a manager of an industrial company with atten- dant social obligations, the pa- tient did not want a removable temporary restoration. Because he was also a busy man, it was desirable to insert an immedi- ate implant with a temporary restoration within 24 hours, depending on the state of the post-extraction alveolus. This procedure involved a minimum number of appointments over a clearly defined period. With the help of the clinical findings and a planning template using a ra- diopaque steel ball (panoramic radiograph; Fig. 2), it was pos- page 20DTà Fig. 7 The radiograph shows the implant with the temporary abutment. The distance from the bone edge to the contact point of the crown is approx. 5mm owing to marginal bone loss. Fig. 8_The impression coping for open impression taking was screwed on. The implant position was transferred to the laboratory with the help of a plastic key. Fig 9 In the laboratory, the dental technician prepared a custom-made titanium abut- ment (Esthetic Abutment) and fashioned the temporary composite crown, which was cemented in place just 24 hours after implantation.
