Choosing a dental delivery unit isn’t about picking the “best model” on paper, it’s about matching the unit to how your operatory actually runs. When your layout, assistant access, cleaning/turnover routine, and room infrastructure align, procedures feel smoother, faster, and more comfortable for everyone.

60-Second Delivery Unit Choice Check
- Workflow: Four-handed dentistry, solo dentistry, or hygiene-first?
- Room reality: Do you have fixed plumbing/air lines—or do you need flexibility?
- Cleaning: Can your turnover routine stay consistent and fast?
- Assistant reach: Can your assistant access the “top 3” tools without twisting?

The 3 Delivery Unit Types (Quick Overview)
| Type | Best for | Watch-outs |
|---|---|---|
| Chair-mounted | Consistent positioning, streamlined rooms, common GP workflows | Some patients dislike over-the-patient setups; chair compatibility matters |
| Cart-mounted | Flexible room layouts, multi-provider spaces, easier repositioning | Hose/cable management and a dedicated “parking spot” are essential |
| Self-contained | Limited infrastructure, temporary rooms, mobile dentistry workflows | Maintenance discipline (water/filters/compressor depending on model) |
Bottom line: The “right” unit is the one that matches your workflow + assistant access + cleaning routine + room infrastructure.
Chair-Mounted Delivery Units: Best for Who?
Chair-mounted delivery systems are often integrated with (or designed around) a dental chair. Many clinics like them because the instrument positions stay predictable, day after day especially useful when you want a consistent, repeatable operatory setup.
- Great fit for: GP operatories, single-provider rooms, clinics prioritizing consistency
- Consider this: Over-the-patient placement can affect patient comfort; arm position and clearance matter

Cart-Mounted Delivery Units: Flexibility + Mobility
Cart-mounted delivery units (freestanding or tethered carts) shine when you need layout flexibility. They can work especially well in larger rooms, shared operatories, or settings where you frequently adjust positioning between providers or procedures.
- Great fit for: multi-provider rooms, larger operatories, changing layouts
- Consider this: cable/hose “drift” can slow turnover plan a consistent parking spot and wipe-down route
Self-Contained Delivery Units: When You Don’t Want Plumbing Headaches
Self-contained delivery systems can reduce dependence on fixed plumbing by using onboard water systems (and depending on the unit, onboard air/compressor support). They’re popular for temporary operatories, build-outs in progress, or mobile workflows.
- Great fit for: limited infrastructure, temporary rooms, mobile dentistry
- Consider this: maintenance and service planning matter build a simple checklist and stick to it
Workflow-Based Chooser (Mini Decision Guide)
Pick by workflow
- Fast GP turnover + consistent setup: chair-mounted
- Shared operatory + flexible positioning: cart-mounted
- Limited infrastructure / temporary room / mobile dentistry: self-contained
The “Assistant Reach Test” (2-Minute Ergonomics Check)
This quick test helps you spot ergonomic friction before you buy. The goal: your assistant should reach the most-used tools without twisting, leaning, or fighting hoses.
- Choose the top 3: HVE + saliva ejector + air/water syringe (assistant side).
- Assume normal working posture: sit exactly as you do in daily procedures.
- One-move rule: can your assistant reach each item without torso twisting?
- Hose drag check: do hoses drop to the floor, cross the sterile field, or snag edges?
- 30-second exchange: run a fast instrument pass, note where the flow breaks.
Cleaning Workflow: Faster Turnover, Fewer Misses
Your delivery unit should support a consistent turnover routine. When the wipe-down path is repeatable and hoses park cleanly, rooms reset faster, and mistakes drop.
Between-patient turnover (6 simple steps)
- Barrier plan: barrier the highest-touch points (switches, handles, pads).
- Dirty-to-clean route: wipe in a consistent order every time.
- Contact time discipline: follow the disinfectant label’s wet contact time.
- Hose management: park hoses in the same spot (avoid floor contact).
- Quick flush: follow your clinic protocol and manufacturer guidance for lines.
- Reset standard: return to a consistent “ready room” baseline.
Note: Always follow your clinic’s infection control protocols and manufacturer instructions for your specific equipment.

Frequently Asked Questions (FAQ)
Q1: Which dental delivery unit type is best for a small operatory?
Smaller rooms often benefit from predictable positioning (often chair-mounted) or a carefully planned cart system with a dedicated parking spot. The key is keeping hoses controlled and preserving a clean turnover path.
Q2: When should I choose a cart-mounted delivery unit?
If multiple providers use the same room, your layout changes often, or you need positioning flexibility, cart-mounted delivery units can be a strong fit.
Q3: What does “self-contained” mean in dental delivery units?
Self-contained systems reduce dependence on fixed plumbing by using onboard water systems (and depending on the unit, onboard air/compressor support). They’re commonly used for temporary rooms and mobile workflows.
Q4: How do I reduce assistant overreaching?
Run the assistant reach test: your assistant’s top three tools should be reachable without twisting. If not, adjust unit type, arm position, or your hose parking point.
Q5: What should be in Phase 1 vs Phase 2?
Phase 1 gets you producing with the essentials. Phase 2 upgrades speed and patient experience with extra ports, integrations, and optimized cabinetry.
Q6: Do you carry dental brands?
Yes. MediDepot’s dental product range includes brands such as Benchmark Scientific, Flight, and Laschal Surgical across relevant categories.
