What Is a Partial Crown?

A partial crown is a fixed dental restoration that only partially covers the tooth — unlike a full crown, which encloses the entire visible tooth. It is used when the defect is too large for a ceramic inlay but too small for a full crown. The principle: Only the damaged areas are replaced, while healthy tooth structure is preserved.

Depending on the extent of the defect, different forms of partial restoration are distinguished:

• Onlay: Covers the chewing surface and one or more tooth cusps
• Overlay: In addition to the cusps, also covers parts of the tooth walls
• Partial crown: Covers more than 50% of the tooth surface but leaves at least one tooth wall free

In practice, these terms are often used interchangeably. The key point is: the partial crown is the most substance-preserving alternative to a full crown and is part of the spectrum of modern dental restorations. Through adhesive bonding, the remaining tooth is additionally stabilised — a significant advantage over conventionally cemented full crowns.

The choice between a partial crown and a full crown depends on several factors. The goal is always: Preserve as much healthy tooth structure as possible while providing as much protection as necessary.

A partial crown is the right choice when:

• Sufficient healthy tooth structure is present (at least 1–2 stable tooth walls)
• The defect is too large for an inlay but does not affect the entire tooth
• The tooth is vital (alive) and adhesive bonding can be applied
• Maximum substance preservation is desired

A full crown is better suited when:

• Less than 50% of the tooth structure remains
• The tooth has been root-treated and is therefore more brittle
• Heavy chewing or grinding loads are present and all-round protection is necessary
• The remaining tooth walls are too thin or at risk of fracture

Think of it as a spectrum: Inlay, Onlay, Partial Crown, Full Crown. The larger the defect, the more coverage is needed. At our practice, we always choose the least invasive restoration that is functionally and long-term reliable. This means: where a partial crown suffices, we do not place a full crown.

Various materials are available for partial crowns, differing in aesthetics, strength and bonding method. The choice of material depends on the position of the tooth, functional requirements and your personal preferences.

Partial crown treatment typically requires two appointments. With CEREC fabrication, same-day completion is often possible.

1. Diagnosis and consultation: Dr. Dickel examines the affected tooth clinically and radiographically. If needed, a CBCT 3D scan is taken. Together we discuss the findings, treatment options (partial crown vs. full crown vs. inlay) and prepare a transparent treatment and cost plan.
2. Substance-preserving preparation: Under local anaesthesia, the tooth is prepared minimally invasively. Unlike a full crown, no circumferential grinding is required — only the defective areas to be covered are prepared. Healthy tooth walls are fully preserved.
3. Impression or digital scan: The preparation is captured either with high-precision silicone material or digitally via intraoral scanner. Precise shade matching is carried out simultaneously.
4. Provisional restoration: A temporary protects the prepared tooth until the definitive partial crown is ready (approx. 1–2 weeks for laboratory fabrication).
5. Laboratory fabrication: Our partner master dental laboratory fabricates the partial crown individually — using CAD/CAM technology or conventional handcraft, depending on material and requirements.
6. Adhesive placement: For ceramic partial crowns, the restoration is adhesively bonded under complete dry-field isolation (rubber dam) — not simply cemented. This step is critical for longevity and tooth stabilisation. The bite is then finely adjusted and polished.

CEREC — partial crown on the same day: As a CEREC-certified practice, we can digitally design and mill ceramic partial crowns on-site in many cases — no temporary, no second appointment.

Adhesive bonding (adhesive technique) is the decisive factor that distinguishes ceramic partial crowns from conventionally cemented restorations — and gives them a unique advantage.

What does adhesive bonding mean? When bonding a ceramic partial crown, both the inner surface of the ceramic (via hydrofluoric acid etching and silanisation) and the tooth surface (via phosphoric acid etching and bonding agent) are chemically pre-treated. A low-viscosity composite cement bonds both surfaces into a monolithic unit. The result: ceramic and tooth form a functional unit.

Tooth-stabilising effect: While a cemented crown merely "covers" the tooth, an adhesively bonded partial crown reinforces the remaining tooth. Studies show that the fracture resistance of the restored tooth approaches that of an intact tooth. This is why ceramic partial crowns achieve comparable or even better survival rates than full crowns despite lower material thickness.

Conventional cementation vs. adhesive technique:

• Cementation: Mechanical retention, no chemical bond, no tooth stabilisation — suitable for gold and zirconia
• Adhesive technique: Chemical bond, tooth-reinforcing, tight marginal seal — the method of choice for pressed ceramic (e.max)

Adhesive bonding requires a dry working field (rubber dam) and technical expertise. At our practice, we are fully proficient in this technique — it is a core element of our substance-preserving treatment philosophy.

Partial crowns are among the most durable dental restorations — with proper care, they last many years and often decades.

Expected longevity by material:

• Gold partial crown: 15–20 years and significantly longer — gold has the longest scientific track record
• Ceramic partial crown (pressed ceramic/e.max): 10–15 years and more — excellent long-term results are documented through adhesive bonding
• Zirconia partial crown: 10–15 years and more — the most robust ceramic option

Daily care: Caring for a partial crown is no different from regular dental care. Brush twice daily with fluoride toothpaste and clean the interdental spaces daily with dental floss or interdental brushes. The transition area between partial crown and tooth requires particularly careful cleaning.

Regular check-ups: Visit us at least twice a year for check-ups and professional dental cleaning. We check the fit of the partial crown, the marginal seal and the condition of the underlying tooth.

Night guard: If you grind your teeth at night (bruxism), the stress can lead to chipping or fractures of ceramic partial crowns. A custom-fitted night guard protects your restoration. Learn more on our page about teeth grinding.

The cost of a partial crown depends on the chosen material, the size of the restoration and laboratory fees. German statutory health insurance pays a fixed diagnosis-based subsidy — the same subsidy as for a full crown, since the dental diagnosis is decisive, not the chosen treatment form.

Billing by material:

• Ceramic partial crown: Classified as alternative dental prosthesis, since the standard provision for the posterior region is a full cast crown. Billing is according to the GOZ (private fee schedule); the fixed subsidy is credited.
• Gold partial crown: Classified as equivalent dental prosthesis (metal restoration like the standard provision, but higher-quality material). Billing is partly according to BEMA; additional costs according to GOZ.

Bonus booklet: Patients who maintain their bonus booklet without gaps receive a higher fixed subsidy — 20% more after 5 years, 30% more after 10 years. This can amount to several hundred euros. Make sure your check-up appointments are recorded regularly.

Full cost transparency: Before every treatment, we prepare a detailed treatment and cost plan (HKP) that you submit to your health insurer. This way you know your exact out-of-pocket cost before treatment begins — no hidden costs, no surprises.

At our dental practice in Munich-Oberfoehring, we combine the latest technology with a substance-preserving treatment philosophy — for partial crowns that meet the highest functional and aesthetic standards.

CEREC — ceramic partial crown on the same day: With our CEREC technology, we can digitally design and mill ceramic partial crowns right in the practice. No silicone impressions, no temporary, no second appointment — your definitive partial crown in a single session.

CBCT 3D diagnostics: For complex cases, we use three-dimensional imaging (cone beam computed tomography). This enables precise assessment of tooth structure, roots and surrounding anatomy — the foundation for the right decision between partial crown, full crown or alternative restoration.

Adhesive technique at the highest level: Adhesive bonding of ceramic partial crowns is one of our core competencies. We routinely work with rubber dam, layered bonding technique and state-of-the-art adhesive systems — for a durable, tooth-reinforcing bond.

Master laboratory for complex cases: For aesthetically particularly demanding situations or large partial crowns, we work closely with our master dental laboratory. The dental technician can personally perform shade matching when needed — for a result that blends seamlessly into your smile.

Treatment for anxious patients: Are you afraid of the dentist? We offer nitrous oxide sedation and twilight sedation so your treatment is stress-free and relaxed.
