Services
Orthodontics
Orthodontics focuses on correcting misaligned teeth and jaws to improve bite function and aesthetics. We treat children and adults with braces, clear aligners, and retainers, tailoring each plan to individual growth and lifestyle. Patients benefit from smoother occlusion, enhanced oral health, and a confident smile.
Periodontics
Periodontics addresses gum disease, bone loss, and supporting structures to preserve natural teeth. We perform scaling, root planing, surgical grafts, and maintenance programs for patients with periodontal concerns. Our interventions protect oral health, reduce tooth loss, and restore functional daily chewing ability.
Dental Implants
Dental implants replace missing teeth with titanium posts that fuse to jawbone, providing a durable foundation for crowns or bridges. We evaluate bone density, design individualized implant placement, and coordinate with restorative specialists to ensure optimal fit and aesthetics. Patients experience restored chewing function, improved facial structure, and longterm oral stability.
Miniimplants
Miniimplants serve as temporary anchorage devices for orthodontic tooth movement without surgical placement of larger implants. We insert small titanium screws into the palate or alveolar bone, providing stable support for brackets and wires. Patients benefit from accelerated alignment, reduced treatment duration, and less invasive procedures.
