Samples were stored in distilled water at room temperature for 24 hours and subsequently tested in shear mode on a universal testing machine Model ; Instron Corp. The debonded interface was recorded and analyzed to determine the predominant bond failure site under an optical microscope Stereomicroscope at 10X magnification. Results Mean SBS of microcrystalline base Conclusion Different base designs of metal and ceramic brackets influence SBS to enamel and all were clinically acceptable.

Keywords: Adhesive precoated base, Fracture sites, Microcrystalline mechanical base, Polymer mesh base, Patented bead ball base Introduction In the direct bonding of orthodontic attachments to the teeth, nature of the enamel surface, the conditioning procedure, the type of adhesive and the design of the bracket base may influence the bond strength [ 1 ]. Ceramic orthodontic brackets were introduced in dentistry in the s to satisfy the aesthetic needs of patients and have been available for clinical use since [ 2 , 3 ].

All currently available ceramic orthodontic brackets are composed of aluminium oxides [ 4 , 5 ] which have many advantages such as biocompatibility, good aesthetics, resistance to temperature and chemical changes, and good bond strength that is higher or equal to that of stainless steel brackets [ 6 — 9 ].

Ceramic bracket bonding mechanisms are divided into three groups: mechanically retentive bases, silane-treated chemically retentive bases, and both mechanically and chemically retentive bases.

Various studies have shown that the bond strength between the ceramic and composite in a silane treated chemically retentive bracket is more as compared to a mechanically retentive ceramic bracket.

This high bond strength is almost equal to the strength of enamel, making enamel fractures more likely to occur [ 9 — 15 ].

Therefore, mechanically retentive ceramic bracket base designs are more desirable than chemically retentive ceramic brackets [ 16 ]. For mechanical retention, various base designs, such as micro-crystalline, mechanical ball, dovetail, dimpled, mechanical, buttons, and polymeric bases are available from many manufacturers.

Furthermore, these designs are claimed to have more consistent bond strengths and debonding characteristics than conventional stainless steel brackets which have a mesh welded to the bracket base to provide mechanical retention [ 3 , 17 , 18 ].

Bonding can be done either by using precoated bracket system or by manually applying adhesive to the bracket base prior to placement [ 19 ]. Precoated brackets were available as both metallic and ceramic types.
