Penn Sharp Biocompatible Product Suite

Orthodontic retainers that keep your smile straight and beautiful

BIOCOMPATIBLE removable retainers

Atlas Titanium Retainer

A next‑generation retainer built on a laser sintered titanium framework.

Benefits

• Inert, medical‑grade titanium

• Intimate fit locks teeth in ideal position

• Rigid, dimensionally stable scaffold

• Superior hygiene and reduced biofilm

• Ultra‑smooth surface for comfort

• Customisable colour options

Ideal for all orthodontic patients with:

• Relapse tendencies

• Crowding or rotation history

• Sensitivity to plastics

• Long‑term retention needs

BIOCOMPATIBLE fixed retainers

Infinity fixed retainer

Penn Sharp’s unique Infinity fixed retainers use inert, corrosion‑resistant materials that avoid the microplastic degradation seen in composite‑bonded fibre retainers.

Advantages

• No compliance concerns

. Ultra-hygienic and easy to clean

• No particulate shedding or corrosion

• Long‑term tissue compatibility

BIOCOMPATIBLE tmd & bruxisum SPLINTS

Atlas Titanium + PEEK Pads

A dual‑material system engineered for occlusal stability and joint decompression. Ideal for bruxers and post-orthodontic patients who need retention and want TMD symptom release

Biocompatible Advantages

• Titanium base: corrosion‑resistant, tissue‑friendly

• PEEK pads: dentine‑like elasticity, no particulate shedding

• Galvanic neutrality

• Smooth surfaces reduce irritation and bacterial adhesion

Indications

• Bruxism

• TMD

• Occlusal instability

• Post‑orthodontic stabilisation

BIOCOMPATIBLE retainers

Our biocompatible retainers—Atlas Removable with its titanium‑reinforced architecture and the Infinity Titanium Fixed Retainer—are engineered to deliver the safest, cleanest and most durable retention available in modern dentistry.

Designed by Dr David Penn and used extensively in the US, both systems eliminate microplastic exposure entirely, using medical‑grade titanium that is inert, corrosion‑proof, and exceptionally hygienic, ensuring no particle shedding and minimal biofilm accumulation.

The Atlas Removable provides a smooth, comfortable, easy‑clean design with long‑term dimensional stability, while Infinity offers a sleek, invisible fixed solution that maintains alignment with absolute precision.

Together, they form a retention suite that is biocompatible, hygienic, and long‑lasting, giving our patients appliances that protect periodontal health, support long‑term stability and integrate seamlessly into daily life without degradation or discoloration.

BIOCOMPATIBLE aligner seaters

Penn Sharp use Munchies: aligner seaters that are engineered from non‑degrading, medical‑grade materials that avoid the microplastic shedding common in EVA‑based seaters.

Benefits

• No particulate release

• High durability

• Hygienic, non‑porous surface

• Safe for long‑term daily use

BIOCOMPATIBLE CROWNS and bridges

Zirconia and PEEK represent the most biocompatible crown materials in modern dentistry that we offer in our practice because both are chemically inert, non‑shedding and engineered to remain stable under long‑term intraoral conditions.

Zirconia’s fully sintered crystalline structure is non‑porous, corrosion‑proof and free of endocrine‑active additives, meaning it does not leach substances into saliva or gingival tissues. Its surface remains stable even under high occlusal load, making it ideal for patients who need strength without biological compromise.

PEEK, meanwhile, offers a dentine‑like elastic modulus, exceptional fatigue resistance, and a polymer backbone that does not fragment into microplastics under chewing, heat or cleaning cycles. This makes it uniquely suited for bruxers, TMD patients, and implant cases where shock absorption and tissue harmony matter.

Together, zirconia and PEEK form the gold standard for biocompatib2le crowns—materials that protect oral tissues, avoid inflammatory contaminants, and deliver long‑term stability without compromising patient health.
