Key Findings: Trends in Dental Cases & US Economy Impact

Dentists expect volume of routine and non-routine visits to increase in 2008

compared to the same quarter in 2007.

For dentists expecting a decrease in visits in 2008, 90% indicate the state of the economy is a factor.

Dentists predicting an increase in visits in 2008 cite practice growth as a factor.

Nearly 80% of respondents currently have a negative to strongly negative perception of the general US economy.

67% of dentists indicate the economy is currently having a negative impact on their practice.

Nearly 60% indicate that the US economy will have a negative on their practice impact 12 months from now.

Currently 15% of dentists feel the US economy is having a positive impact on their practice, yet over 30% indicate the economy will have a positive effect 12 months from now.

While respondents were split on awareness of new tax incentives, almost 32% will make an equipment technology purchase in 2008 because of the tax incentives.

The tax incentive will influence respondents to purchase new equipment, digital x-rays, large ticket items, and replace failures instead of fixing them.

Close to 63% of those making new equipment or technology purchases will spend $50,000 or more, which for 60% of respondents represents an increase in spending from 2007 by an average of 70%.

Key Findings: Consumables, Basic Equipment, and High Tech Equipment

72% of consumables purchased are from primary distributors; Henry Schein is most

commonly used.

Over 80% of dentists will not change the percent of total purchases supplied by their primary consumables distributor.

68% of dentists purchase 16% of their consumables directly from manufacturers.

Choice of distributor is primarily driven by price (mean rank 1.8) followed by most consumable SKUs (breadth of

products) (mean rank 3.1).

Over 65% of total basic equipment purchases are made from primary consumables

distributors.

80% of high-tech equipment is purchased through either primary consumables

distributors (53%) or direct from the manufacturer (27%).

Digital x-ray (mean rank 1.5) is considered the most important high-tech equipment to dental practices, followed by the

intra-oral camera (mean rank 2.3).

Outside of digital x-ray and CAD/CAM, respondents indicate laser dentistry, cone beam/CT, electronic records, and

digital impressions as being the most promising new technologies in the next 5 years.

Key Findings: Digital X-Ray

76% of dentists are performing intra-oral imaging, 65% are doing panoramic, 11% are

doing neither.

Both intra-oral and panoramic users indicate digital is more beneficial than film, panoramic users slightly more so, 63%

to 61% respectively.

Respondents estimate nearly a third of US dentists are currently using digital x-ray.

A 26% CAGR expected in digital x-ray use over the next 3 years.

Of the 42% of respondents without digital x-ray, 19% anticipate purchasing a system

in 2008.

Over 68% of respondents are aware of 3-D x-ray systems, 60% of them see a need within their practice for one and

34% of those who see a need plan to purchase a system within the next 3 years.

Key Findings: Trends in Dental Implant Cases

Respondents perform an average of 7.8 implant cases per month, 60% of which are non-

elective.

For the 15% of respondents that switched implant brands, most are leaving Nobel Biocare, going to either Straumann, or Astra, for

various reasons.

77% of dentists said price was not the most significant factor in choosing an implant manufacturer, ease of use and reliability are

indicated as factors influencing selection.

Respondents report a consistent increase in the number of dental implant case starts over

2007, (16.5 in Q2 07) and they project the number to continually increase reaching 20.1 case

starts per month by Q1 in 09.

The economy and energy prices are indicated as factors for those anticipating a decrease in case starts in Q2 2008 compared to Q2

Advertising/marketing and increased awareness are factors given for seeing an increase in case starts from Q2 2007 to Q2 2008.

70% of dentists have not seen a change in outward referrals for dental implants in the past 12

months.

26% have seen an increase by 26%. Reasons indicated for the increase include better patient education and awareness.

5% have seen a decrease in outward referrals by 33%. Primarily because they are capable of doing implants themselves instead of

referring out.

Key Findings: CAD/CAM

65% of respondents feel the average 29 crown restorations they perform a month will

not change over the next 12 months. 32% believe they will see an increase by 12%.

Respondents recognize a mean difference of $785.67 between the amount charged

per crown and the amount paid in lab fees per crown. More dentists are paid cash by

patients than through managed care.

While all respondents are aware of CAD/CAM 60% are not using it.

60% of respondents indicate cost as the primary reason they have not purchased an in-office CAD/CAM system,

followed by lack of necessity for 27%.

Of the 16% considering purchasing CAD/CAM, it would be in an average of 3.3 years.

25% of those are considering the E4D from D4D.

A 15% CAGR is expected for in-office CAD/CAM system use over the next 5 years.
