STATEMENT OF THE PROBLEM: Recent data regarding the effects the cement type and abutment heights on the retentive force of a
prosthetic crown are inconsistent and unable to suggest clinical guidelines. PURPOSE OF THE STUDY: This study evaluated the effects
of different types of temporary cements and abutment heights on the retentive strength of cement-retained implant-supported prostheses.
MATERIALS AND METHODS: Prefabricated implant abutments, 4 mm in diameter, 8�taper per side, and light chamfer margins, were
used. The abutment heights of the implants were 4 mm, 5.5 mm and 7 mm. Seven specimens of a single crown similar to a first premolar
were fabricated. Six commercially available temporary cements, TempBond, TempBond NE, Cavitec, Procem, Dycal, and IRM, were used
in this study. Twenty-four hours after cementation, the retentive strengths were measured using a universal testing machine with a crosshead
speed of 0.5 mm/min. The cementation procedures were repeated 3 times. The data was analyzed using two-way analysis of variance
and a Tukey test (α=0.05). RESULTS: The tensile bond strength ranged from 1.76 kg to 19.98 kg. The lowest tensile strengths were similar
in the TempBond and Cavitec agents. Dycal showed the highest tensile bond strength (P<0.01). More force was required to remove the
crowns cemented to the long abutments (P<0.05). CONCLUSION: TempBond and Cavitec agents showed the lowest mean tensile bond
strength. The Dycal agent showed more than double the tensile bond strength of the TempBond agent.
