“…The retentive strength of unthreaded, tapered posts is well known to be inferior to that of parallel or any other kind of threaded posts (Hudis & Goldstein, 1986; Ricker et al ., 1986; Torbjörner et al ., 1995). However, previous research on tapered post systems showed adequate retention for clinical use (Brown & Mitchem, 1987; Weine et al ., 1991; Morgano, 1996; Zuckerman, 1996). Their small constant angle of divergence should have a similar effect with the conicity of crowns to achieve friction.…”

“…The advantages of prefabricated posts for the restoration of the teeth with missing coronal structure are well documented. In the long term clinical success, physical and mechanical factors influencing the retentive properties of the posts are important (Caputo & Standlee, 1976; Wood, 1983; Hudis & Goldstein, 1986; Nathanson & Ashayeri, 1990; Morgano, 1996; Zuckerman, 1996). Prefabricated posts are advantageous in cases where not too much coronal tooth structure is missing.…”

The force transmission of tapered unthreaded posts along the root has been reported to be homogenous but their retentive strength was found to be lower compared with those of parallel unthreaded or other kinds of threaded posts. The purpose of this in vitro study was to investigate the effect of length and diameter on the retentive strength of sandblasted tapered prefabricated titanium posts (Erlangen post system). Posts with constant taper angle but with three different lengths (9, 12, 15 mm) and apical diameters (0.5, 0.9, 1.1 mm) were cemented using zinc phosphate cement into the prepared and roughened post spaces of 90 intact anterior teeth. The post retention concerning length and diameter, being independent from each other, was measured by a tensile force test. The retentive strength was found to be proportional to the length as well as to the diameter of the posts. The mean minimum strength (181 +/- 14 N) recorded for the thinnest and shortest post was significantly lower than that of mean maximum strength (612 +/- 85 N) obtained from those of the thickest and longest post. Proportional bond strengths of the posts comprising their surface areas ranged between 6.8 and 7.9 N mm(-2) which were not significantly different between any group. The retention was effected strongly with the increase in the length (approximately 100%) than with the increase in the diameter (approximately 60%). Concerning the posts tested in this study, it is concluded that some caution should be exercised in the choice of post with appropriate length rather than diameter for the tooth concerned.

“…Many causes of failure of post and core retained restorations have been identifi ed, including: recurrent caries, endodontic failure, periodontal disease, post dislodgement, cement failure, post-core separation, crowncore separation, loss of post retention, core fracture, loss of crown retention, post distortion, post fracture, tooth fracture, and root fracture. Also, corrosion of metallic posts also has been proposed as causes of fracture [4][5][6].…”

Restoration of severely fractured/ decayed teeth requires crown restoration after endodontic therapy which is often major requisite in conservative dentistry. If there is steep incisal guidance and very less overjet then restoration of such crown is not possible with routine post and core followed by crown restoration because of very less incisal clearance. Richmond crown is advisable in such cases as it is single-unit post retained crown with porcelain facing design. Two cases have been discussed here with Richmond crown treatment modality over 2-3 years successful follow-up.

“…Döküm postlar, sağlam dentin dokusunu koruma, adaptasyon ve tutuculuk açısından yuvarlak kesitli prefabrik postlara göre üstün özellikler gösterir. 15 Ancak geleneksel döküm postların, uzun laboratuvar işlemleri nedeniyle zaman alıcı olmaları, elastisiteleri dentinden yüksek olduğundan ötürü kırıklara yol açmaları ve korozyona uğrayarak estetik beklentileri karşılayamamaları, araştırıcıları farklı post sistemlerine yönlendirmiştir. [16][17][18] Seramikler, estetik, biyouyumlu ve yüksek kırılma dayanımına sahip materyaller olarak post uygulamalarında da kullanılmıştır.…”

Aim: This original research study aimed to evaluate the effect of Er:YAG laser irradiation of post spaces prepared in oval root canals on the push-out bond strenght of zirconia posts manufactured by Computer Aided Design / Computer Aided Manufacturing (CAD/CAM) technology. Materials and Methods: Forty teeth showing oval root canal configuration were included to the study following the radiological examination. Post spaces were prepared with ultrasonic tips after the completion of root canal treatment. Specimens were divided into two groups randomly either they were irradiated with Er:YAG lasers or not (n=20). For each specimen, zirconium posts were produced by milling from yttria-tetragonal zirconia polycrystal (Y-TZP) blocks. Posts were sintered and luted in the post spaces of specimens. Push-out bond strenght test was performed and data was statistically analyzed using ttest and chi-square test. Results: The push-out bond strenght values of the group, which specimens were irradiated with Er:YAG laser were significantly higher when compared to nonlased group (p<0.05). Conclusion: Er:YAG laser pretreatment of radicular dentin improved the push-out bond strenght values.
